Are electrons that are in the outermost shell.

A metal is a hard or shiny element found on the periodic table .

A period is a side to side area where the elements are on the table .

They are reactive non metals and are very acidic .

They are very unreactive elements .

A ion has a net charge due to a added proton neutron or electron .

A atomic number is what tells you the protons and electrons .

The mass number tells you the mass of the atom which can also be used to find the neutrons .

Is two or more of the same element , but have different amounts of neutrons .

AMU

It is when the masses of all isotopes of s element are added by the natural abundance .

It is when the atomic mass is rounded to the nearest hundredth .
