Sodium fluoride (NaF)

product of ionic bonding, and it is used in dental products. It makes teeth more resistant to bacteria and decay, preventing cavities.

Ion

an atom or group of atoms that has gained or lost its valence electrons.

Molecule

is made up of two or more atoms with a definite arrangement that are held together by a chemical bond.

cation

ion that carries a net positive charge.

anion

an ion that carries a net negative charge.

Monoatomic ion

is an ion that contains only one type of atom

polyatomic ion

two or more types of atoms in the ion

Protons

The number of ____ in the nucleus of each atom remains the same during chemical bond,

Calcium chloride

used to melt ice n snow

Barium chloride

used to make green fireworks

Cobalt chloride

used to detect moisture n changes color when absorbs water

Potassium iodide

tablets given to people who are exposed to high levels of radiation

electrolyte solutions

given to children who have lost ions

lithium iodide

used in batteries

oxidation

-Is the total number of electrons that an atom gains or loses to form a chemical bond with another atom to achieve a neutral state again.
-Also referred to as oxidation state.

Chemical formula

Representation of a molecule that uses chemical symbols to indicate the types of atoms followed by subscripts to show the number of atoms of each type in the molecule

Subscripts

indicate the number of atoms of an element.

Parenthesis

used to separate polyatomic ion from the rest of the formula.

Binary compounds

contains only 2 elements
-ionic n molecular

ternary compounds

contains 3 elements
-metal and an oxyanion
-h and an oxyanion
