Section 1 stability in bonding

Chemical formula

Chemical shorthand that uses symbols to tell what element are in a compound

Chemically stable

Describe an atom whose outer energy level is completely filled with all the electrons allowed in that level

Chemical bond

Force that holds atom together in a compound

Ion

Charged particles that has or fewer electron than protons

Ionic bond

Attraction formed between oppositely charged ions an ionic compound

Molecule

a group of atoms bonded together

Polar molecule

Molecules with a slightly positive end and a slightly negative end ad a result of electrons being shared

Nonpolar molecule

Molecule that shares electrons equally and does not have oppositely charged ends

Covalent bond

Attraction formed between atoms when they share electrons

Binary compound

Compound that is composed of two elements

Polyatomic ion

...

Oxidation number

Positive and negative number that indicates how many electrons an atom has gained lost or shared to become stable

Hydrate

Compound that has water chemically attached to its ions written into its chemical formula
