A combination of two or more types of matter that retain their own individual properties

A subatomic particle that has almost no mass and a negative charge.

The number of protons in the atom of a particular element that is unique only to that element

A positively charged subatomic particle located in the nucleus and has an atomic mass of 1

A collection of orbitals around the nucleus, each having its own energy level

A subatomic particle located in the nucleus with no charge

Matter can not be created nor destroyed

If the equation balances it supports

A table of the chemical elements arranged in order of atomic number

Columns, Families and Reactivity all describe

The horizontal row where atomic mass increases as it moves from left to right indicating energy shells.

Groups are organized by valance electrons which also indicates

Elements that are highly reactive and located in group/family 1 on the Periodic Table

The least reactive group on the periodic table

Vertical columns on the Periodic Table

Reactivity on the periodic table is organized in

Atomic identity is determined by

The number of protons plus the number of neutrons contained in an atoms nucleus

The number "in front " of an element or compound that indicates the number of molecules in a chemical formula

The type of change that results in the formation of a new chemical substance

The type of change in which the form of matter is altered, but "Not changed or transformed "

Group 17 has 7 valance electrons they like to react with group one. The groups name means "SALT FORMERS" This groups name is called the......
