answer
Group 3A |
question
| An atom which forms a -3 ion would most likely be in which family? |
answer
group 5A (the Nitrogen family) |
question
| When combined with the element sulfur, which one of the following elements would most likely come first in the formula? Br F Si O |
answer
| Si (because it is further to the left in the periodic table - more metallic - and would tend to lose electrons to the sulfur to become the (+) cation. |

question
| Calculate the % of oxygen in the compound, dinitrogen tetraoxide. |
answer
dinitrogen tetraoxide = N2O4; (F.W. = 92) 64/92 X 100 = 69.6% oxygen |
question
| Calculate the % of nitrogen in nitrogen triiodide. |
answer
nitrogen;triiodide = NI3; (F.W. = 394.7) 14/394.7 X 100 = 3.5 % nitrogen |
