When non-metals combine with non-metals, both elements in the binary compound are trying to _____ electrons.
GAIN
Whenever Iron forms a compound with a non-metal, a ________ must appear in the name to indicate the valence of Iron.
ROMAN NUMERAL
Which family in the periodic table does not form binary compounds?

GROUP 8A

(the Nobel or Inert Gases)

Metals will never form bonds with metals because both atoms are trying to _____ electrons.
LOSE
An atom that always forms a +3 ion would most likely be in which family?

Group 3A

An atom which forms a -3 ion would most likely be in which family?

group 5A

 (the Nitrogen family)

When combined with the element sulfur, which one of the following elements would most likely come first in the formula? Br F Si O
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.
ALL binary compounds end in the suffix _____.
"ide"
Which of the following elements would most likely form an anion? Fe Cl Ga Cs Mg
Cl (it’s the only non-metal in the list;and would most likely gain electrons because it would;have the highest electronegativity value)
CuBr
copper I bromide

vanadium I sulfide

V2S

diphosphorus trisulfide

P2S3

MoS2

Molybdinum IV sulfide

Calculate the % of oxygen in the compound, dinitrogen tetraoxide.

dinitrogen tetraoxide = N2O4; (F.W. = 92)
64/92 X 100 = 69.6% oxygen

Calculate the % of nitrogen in nitrogen triiodide.

nitrogen;triiodide = NI3; (F.W. = 394.7)
14/394.7 X 100 = 3.5 % nitrogen

A compound is found to contain 70.0 % Iron and 30.0 % oxygen.; Determine the empirical formula from the above information and name the compound.

Fe2O3

Iron III oxide

;

Step 1:; divide the percent by the element;F.W. from the periodic table

Step 2:; divide the largest by the smallest numbers from the above step to get the empirical formula.

How many grams are in 2.75 moles of Molybdinum sulfide?

One mole of MoS2 is equal to the formula weight of 160.2 grams.

2.75 mole x 160.2 grams; =; 441 grams
;;;;;;;;;;;;;;;;;;;;;1 mole

PCl3

137.5 grams
