Notes

Atoms (Part 2): All matter is made up of atoms The different types of atoms are called elements

Atoms are made of 3 sub-atomic particles……protons (are the blue circles)…neutrons (are the green circles)…electrons (are the orange circles)

Note: Protons and neutrons are found in thecenter area called the nucleusNote: In atoms the number of protons andelectrons are always the same (3 in this case)

SPI 0807.9.1 Atoms

Here is a model of one lithium atom

Protons: positive charge, found in the nucleus of atoms The number of protons is the atomic number (3 in this case)Note: In atoms the number of protons & electrons are the sameNeutrons: no charge, also found in the nucleus of atomsElectrons: negative charge, found in electron shells in the

electron cloud

Atomic Mass Atoms are very small particles of matter, and everything that is

made of matter has mass Most of the mass of an atom is found in the nucleus• About 99.9% of the mass of an atom is in the nucleus

Nuclear Particles The two particles in the nucleus, protons and neutrons, make up

99.9 % of the mass of the atom

Electrons are located in the electron cloud in areas called electron shells

This atom has 2 electron shells.
