What did Ernest Rutherford do?
Gold Foil Experiment- alpha particles were shot at a piece of gold foil. Some refracted which led to the conclusion of protons being in the center of the atom.
Name the following compound:
Ca3(PO4)2
Calcium Phosphate
What VSEPR (molecular geometry) shape does a substance with only 2 atoms have?
Linear
What is a property that group I and group II share on the periodic table?
React with water (group 1 reacts explosively!)
Convert 2.37 grams of CaCl2 into ions of Cl
2.57 E 22 ions Cl
Why do we not include the noble gases in the electronegativity trend?
They are mostly unreactive (full valence shell), so they don't need to attract.
What is the formula for Copper (II) Chloride?

H, Na, Rb, K
Rb
Convert 5.5 E 27 formula units of MgO to ions of Mg
5.5 E 27 ions of Mg
What did J.J. Thomson discover?
