Question

1. Calcium ion 6. C-4 2. Phosphide ion 7. Rb+1 3. Iodide ion 8. Pb+4 4. Gallium ion 9. S-2 5. Titanium(IV) ion 10. Cr+2 Write formulas/charges or names as appropriate for each of the following monatomic ions.

Answer 1

Ions are atoms that have a charge; they can be positively charged if they have fewer electrons than protons or negatively charged if they have more electrons than protons. When an ion has a negative charge it is called an anion and when it has a positive charge it is called a cation.

Knowing this, let's develop the exercise:

1. Calcium ion ---> Ca+2

2. Phosphide ion ---> P-3

3. Iodide ion ---> I-1

4. Gallium ion --->Ga+3

5. Titanium (IV) ion ---> Ti+4

6. C-4 ---> Carbide ion

7. Rb +1 --->Rubidium ion

8. Pb+4 --->Lead(IV) ion

9. S-2 --->Sulfide ion

10. Cr+2--->Chromium(II) ion
