Question

I am confused and don't know which one to put ide on please help.

For each negative ion listed. Write what it's formula with Ca2+

Calcium 2+ Chloride-
Calcium 2+ Sulfur
Calcium 2+ potassium 3-
Calcium 2+ Nitrogen 3-
Calcium 2+ Bromine -

Answer 1

You would change the ending of the anion, in this case, Chlorine, Sulfur, Phosphorus (I believe is what you mean), Nitrogen, and Bromine to -ide

Answer 2

For future reference, when naming ionic compounds, you would change the anion, or negative ion, (never the cation/positive ion) to -ide if it's a monatomic ion of the element.

Answer 3

How would I write those correctly? Sulfuide like that

Answer 4

You would change the the -ur to an -ide. Giving you:
Sulfide

The others would be:
Chloride
Phosphide
Nitride
Bromide

Keep the root word and change the ending to an -ide. If you're ever unsure, type it into google to double check :)

Answer 5

Thank you soooo much!

Answer 6
