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

Write the formulas for 2 acids and for 2 bases. Tables K + L

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
