Predict the formula for a compound made from X+ and Y–.?

I have a couple of questions regarding chemical compounds and electron configurations:

1) I believe the formula for the compound made from X+ and Y– is XY2. Is this correct or incorrect? Could you please explain why?

2) Can you help me with naming the following compounds? I think my answers were wrong: - MnCl2 - SiCl2 - SrCl2

3) Lastly, I would like to know the ground state electron configuration of tungsten (W) using the noble-gas shorthand notation. I wrote [Xe] 6s² 4f¹ 5d⁴. Is this correct or incorrect? Please provide an explanation.

1. If X is plus one charge and Y is negative one charge, then the answer should be XY.

  1. a.Manganese(II) Chloride

    b.Sulfur Dichloride

    c.Strontium Chloride

  2. [Xe] 4f14 5d4 6s2

The correct formula is XY. One pos. charge and one neg. charge add up to zero.

manganese(II) chloride

sulfur dichloride

strontium chloride
