Matter – Atoms and Elements Review

lesson @discoveryed.com

Essential Standards• NCES.6.P.2 - Understand the structure,

classifications and physical properties of matter

• NCES.6.p.2.1- Recognize that all matter is made up of atoms and atoms of the same element are all alike, but are different from the atoms of other elements.

9/9/2015 Warm-UP• Science is all about puzzling questions:

1. Matter is made up of tiny particles called “atoms.”

How many atoms do you think are in a single drop of water?

2. Name the 3 subatomic particles?

Lesson Questions:• 1. What is the relationship between

atoms and elements?

• 2. How are atoms of one element similar to and different from atoms of other elements?

• Key Vocabulary• atom, element, energy (physical),  

mass, • matter, molecule,

Matter is varied because it is

composed of different elements. • Introduction to atomic structure - DE video• http://app.discoveryeducation.com/player/view/as

• How do we know about atoms and elements?

• After all, these are very tiny –too small to see even with a normal microscope.

• Only very powerful microscopes are able to be used to see atoms.

• Atoms are made of PROTONS, NEUTRONS & ELECTRONS

• Neutrons and protons are located IN the nucleus of an atom

• Electrons orbit AROUND the nucleus.

• Protons are positively charged• Neutrons are neutral – no charge• Electrons are negatively charged

• #1 - What Is the Relationship between Atoms and Elements?    • An element is matter in which all of the atoms  contain the same number of protons. 

• The number of protons in the nucleus of an atom determine what element the atom is.

• An atom of an element never gains or loses protons.

• #2 - How Are Atoms of One Element Similar to and Different from Atoms of Other Elements?    

• SIMILAR:• All atoms, even atoms of different

elements, are made of protons, neutrons, and electrons.

• DIFFERENT:• Atoms of one element have a different

number of protons in the nucleus than the atoms of a different element.

What Are Ions and Why Do They

Have Different Charges?  • Although atoms of the same element

always have the same number of protons in their nucleus, they can have a different number of electrons.

• The atomic number of an element is also called a proton number. The proton number tells you the number of protons or positive particles in the nucleus of an atom.

 

• A normal atom has a neutral charge when there are equal numbers of positive and negative particles.

SO

• An atom with a neutral charge is one where the number of electrons is equal to the atomic number or the number of protons.

• Ions are atoms with extra electrons or missing electrons.

• When you are missing an electron or two, you have a positive charge. oThere are more positively charged

protons than there are electrons.• When you have an extra electron or

two, you have a negative charge. oThere are more negatively charged

electrons than there are protons

• The electrons in the atoms of an element determine the element's chemical and physical properties.

9/10 Warm UP• Number your comp book from 1-6 and fill in

Chrome Book Policy• 1. You only use the chrome book assigned

to you.• 2. Report any damage immediately to me!• 3. You must carry your chrome book by the

base with 2 hands!• 4. You will keep it flat on your desk at all

times…no walking around the room with your chrome book open or closed unless it is closed and you are getting it or putting it away.

• If the next user cannot locate or the battery is not charged due to your lack of responsibility and reliability, you will be held accountable.

• If you find that the prior student has made any inappropriate uses of the chrome book, you must report this to me immediately… because as far as I know the last user was YOU!!!

• Quiz Review!!!!!!!!!!!

• What do the terms melting point and freezing point mean and how are they related?

• What do the terms boiling point and condensation point mean and how are they related?

• What happens to molecular energy when a substance changes state?

• What happens to molecular motion when a substance is heated or cooled?

• What happens to the overall mass of a substance when it changes state?

Quiz Review• _______________ have a definite shape and

volume• The ______________point is the temperature at

which a substance changes from a solid to a liquid.

• The _____________ point is the temperature at which a substance changes from a gas to a liquid.

• Matter is made of tiny particles called ________________.

• The _____________ point is the temperature at which a substance changes from a liquid to a gas

• Atoms combine to form ______________________.

• Temperature is a measure of the ________________ or energy of motion, of the particles of matter.

• _______________ do not have a definite shape of volume.

• _______________ do not have a definite shape, but they do have a definite volume.

• The _____________ point is the temperature at which a substance changes from a liquid to a solid.

Rest of Today:1. Quiz2. After Quiz - When you finish quiz – you will get your chrome book and finish your guided notes from yesterday and/or begin research for your element investigation project.3. When all quizzes are in we will go over the

guided notes and do a review of the atoms and elements lesson BRAINPOP STYLE

9/11 Warm-UP• Please complete the handout

I gave you as you walked in the door!

• Please staple this into your composition book

• Please update your table of contents

Guided Notes• Let’s go over…..• Remember - The number of

protons=the atomic number

Review – Atoms and Elements

• 1. What is the relationship between atoms and 

elements?• An atom is the smallest particle in an element

that retains the properties of that element. • 2. How are atoms of one element similar to

and different from atoms of other elements? Similar - Every atom contains a nucleus, which contains. protons and neutrons . The nucleus is surrounded by electrons. All atoms of the same element have the same number of protons in their nuclei. Atoms of different elements have different numbers of protons in their nuclei.

Review – Atoms and Elements

• 1. What is the relationship between atoms 

and elements?• An atom is the smallest particle in an

element that keeps the properties of that element.

•  An element is matter in which all of the atoms  contain the same number of protons. 

• The atomic number of an element is the number of protons in the nucleus

• The atomic mass is the mass of the protons, neutrons and electrons

• 2. How are atoms of one element similar to and different from atoms of other elements?

Similar - Every atom contains a nucleus, which contains. protons and neutrons . The nucleus is surrounded by electrons. Different - All atoms of the same element have the same number of protons in their nuclei. Atoms of different elements have different numbers of protons in their nuclei.

• The periodic table is a chart containing information about the atoms that make up all matter.

• An element is a substance made up of only one type of atom.

• Atomic number = # of protons

• The number of electrons surrounding the nucleus of an atom is equal to the number of protons in its nucleus.

• Element - Calcium • Symbol - Ca• ATOMIC NUMBER – 20; there are 20 protons

in nucleus • Ca will have ________ # of ELECTRONS?• Atomic Mass -The atomic mass of an

element is based on the mass of the protons, neutrons, and electrons of the atoms of that

element.The majority of the atomic mass is contributed by the protons and neutrons. Electrons don't have much of a mass when compared to a neutron or proton. 

20

CaCalcium

40.078

• A normal atom has a neutral charge when there are equal numbers of positive and negative particles.

SO

• An atom with a neutral charge# OF ELECTRONS = # OF PROTONS

• Ions are atoms with extra electrons or missing electrons.

• When you are missing an electron or two, you have a ________________ charge.

• When you have an extra electron or two, you have a ________________charge.

• Partner Work – Work sheet - What is Matter ?

• When you have completed the worksheet; see Mrs. Henrie for worksheet checkoMake corrections as needed

• Work on Project – DUE TOMORROW• Unit test on FRIDAY

Student Project• Conduct an investigation of one element on

the periodic table! (100pts)1. Pick an element to investigate2. Illustrate your element’s name, atomic number, symbol and atomic mass3. Research and present some basic information about your element to the class. The presentation can be in the form of a poster, pamphlet, PowerPoint presentation or other form. The presentations should be short and can include: atom’s name, atomic number, where the name came from, when and where it was discovered, natural sources of the element, major uses, and any other information you find important.
