Front

Valence Electrons

Back

The electrons in the outer energy level of an atom. These are the ones that can be lost, gained, or shared to form compounds.

Front

Ionic Compound

Back

A compound made out of a cation, an atom that has lost one or more electrons, bonded to an anion, an atom that has gained one or more electrons.

Front

Ionic Bonding

Back

A type of bond that has electrons transferred from one atom to another. Usually happens between a metal cation and nonmetal anion.

Front

Molecular Covalent Bonding

Back

A type of bond that has electrons shared between different atoms. Makes individual units called molecules.

Front

Metallic Bonding

Back

A type of bond that has valence electrons shared between metal atoms.

Front

Halogens

Back

The elements found in group 7A (17) on the periodic table.

Front

Noble Gases

Back

The elements found in group 8A (18) on the periodic table. These are typically unreactive.

Front

Alkali Metals

Back

The elements found in group 1A (1) on the periodic table. These are typically very reactive.

Front

Alkali Earth Metals

Back

The elements found in group 2A (2) on the periodic table. These are typically not as reactive as the alkali metals.

Front

Molecule

Back

A group of atoms attached by covalent bonds.
