Electron Dot Structures

Back

Diagrams that show valence electrons as dots.

Front

Formula Unit

Back

The lowest whole number ratio of ions in an atomic compound.

Ionic Compounds

Back

Compounds composed of cations and anions.

Metallic Bonds

Back

Consist of the attraction of the free-floating valence electrons for the positively charged metal ions.

Valence Electrons

Back

Electrons in the highest occupied energy level of an element’s atoms.

Front

Cation

Back

A positively charged ion, meaning an atom or molecule that has lost one or more electrons, resulting in more protons than electrons.
