Review Class for Naming Compounds
Sit with some new people, and say,
“hello, my name is
__________,
say your name
let’s work together, okay?”
Paper, pen, reference tables ONLY. Clear desks now.

What are the HONClBrIF twins?
Write the formulas for 2 acids
and for 2 bases.
HONClBrIF reminds you of the 7
diatomic elements, hydrogen,
oxygen, nitrogen, chlorine,
bromine, iodine and fluorine, all
have H2 or Br2 type formulas

X Cr does +2, +3, +6 ions
X Zn NO roman numeral
X carbon makes CO,CO2
X argon doen’t react ever
YES, it’s hydrochloric acid
YES, SnF4 - in toothpaste
YES, Hg makes a +2 ion
X, Nb only does +3 & +5
X, metal first always!
X, Mg+2 + Br-1 = MgBr2
