Review of Nomenclature and Electron Dot Diagrams
2
Name the following: HBr(g) Hydrogen bromide HBr(aq) Hydrobromic acid HF(aq) Hydrofluoric acid HI(aq) Hydroiodic acid H2C2O4(aq) Oxalic acid H2CrO4(aq) Chromic acid HClO2(aq) Chlorous acid HClO4(aq) Perchloric acid
3
Name the following: diphosphorus trioxide P2O3 Cr2O3 chromium III oxide AgOH silver hydroxide
4
valence electrons 1e- 7e- 8e- 3e- 4e- 5e- 6e- 2e-
5
When filling in valence electrons, fill electrons in individually then pair them up.
Br has 7 valence e- 6 nonbonding electrons Br Bonding electron
