Chapter 5 Vocabulary

These are the reactive metals located in Group 2 of the periodic table. These elements have two electrons in their outer energy level which makes them reactive with water and halogens.

Alkaline Earth Metals

This is a group of elements from the periodic table that have their outer level electrons in the same period as the row in which they are located.

Representative Elements(Main Group Elements)

This is the distance from the center of the nucleus of an atom to its outermost electron.

Atomic Radius

This is the amount of energy required to remove the outermost electron from an atom.

Ionization Energy

This is the highly reactive family of elements with 7 valence electrons.

Halogens

An electron in the highest occupied energy level of an atom.

Valence Electron

In a circle or sphere, this is any line segment from its center to its perimeter.

Radius

This is a characteristic of the elements in the periodic table that shows a pattern. It may increase or decrease across or down the table.

Periodic Trend

These are the highly reactive elements located in Group 1 of the periodic table. These elements have one electron in their outer energy level which makes them highly reactive with water and halogens.

Alkali Metals

This is the amount of “pull” an atom has for an electron in a chemical bond.

Electronegativity

This is a group of elements with few valence electrons that conducts heat and electricity.

Metals

One class of elements having properties intermediate to metals and nonmentals.

Metalloids

This is the repetition of chemical properties when organized by their atomic number, first noticed by Mendeleev.

Periodicity

The decrease in attraction of outer electrons of larger atoms due to the repulsion from inner shell electrons.

Shielding Effect

A positively charged ion

Cation

This is an element with full valence shell, very unreactive.

Noble Gas
