Sit with some new people, and say,
“hello, my name is __________,
let’s work together, okay?”
say your name
Paper, pen, reference tables ONLY. Clear desks now.
For each slide there are 2 compounds, tell if each is Ionic or Molecular
Write the name or formula for each
Dinitrogen monoxide
ScPO4
Ionic/Molecular? Ionic/Molecular?
What’s the formula?
What’s the official name?
nickel (III) bromide
vanadium (V)sulfide
Ionic/Molecular? Ionic/Molecular?
what’s the formula?
what’s the formula?
tantalum chloride
SiO2
Ionic/Molecular? Ionic/Molecular?
What’s the formula?
What’s the official name?
HONClBrIF reminds you of the 7 diatomic elements, hydrogen, oxygen, nitrogen, chlorine, bromine, iodine and fluorine, all have H2 or Br2 type formulas
Write the formulas for 2 acids and for 2 bases. Tables K + L
What are all the phosphorous – chlorine compounds?
P Cl-3 -1+3 +1+5 +5 +7
PCl3 phosphorous trichloride
PCl5 phosphorous pentachloride
PCl7 phosphorous heptachloride
PCl3 again
PCl5 again
In our class there are only 3 phosphorous – chlorine compounds.

X Cr does +2, +3, +6 ionsX Zn NO roman numeralX carbon makes CO,CO2
X argon doen’t react everYES, it’s hydrochloric acidYES, SnF4 - in toothpasteYES, Hg makes a +2 ionX, Nb only does +3 & +5X, metal first always!X, Mg+2 + Br-1 = MgBr2
