What is a chemical bond?
Formed from valence electrons which hold two or more atoms together in a compound
The type of chemical bond found in ionic compounds. It is formed from a transfer of valence electrons from the cation to the anion.
The chemical formula for an ionic compound. Specifically, it is the lowest whole number ratio (reduced form) of ions in an ionic compound.
a compound composed of cations and anions (metals, non metals, Polyatomic ions)
What is an ionic compound?
Formed from valence electrons which hold two or more atoms together in a compound
a substance that contains two or more elements chemically combined (bonded together)

What are valence electrons?
The electrons in the highest occupied energy level of an elements atoms
Group 1A elements all have one valence electron (all end in S^1)
a substance that contains two or more elements chemically combined (bonded together)
diagrams that show the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
the electrons in the middle of a nucleus
