ATOMIC STRUCTURE Review NAME: ____________________________ Date:____ Block:__
Use your periodic table to answer the following questions and fill out the following tables.
Subatomic Particle
Charge
Mass
Location
Formula
Proton
(defines the type of atom)
+1
1
Nucleus
= atomic number
Neutron
0
1
Nucleus
= mass number – atomic number
Electron
-1
0
Electron clouds
orbiting the nucleus
= atomic number – charge
p+ = e- in a neutral atom
If there is a negative charge the ion has more electrons than protons (gained e- to become an anion)
If there is a positive charge the ion has less electrons than protons (lost e- to become a cation)
