Use of the Data Booklet is relevant to this question. Why is the ionic radius of a sulfide ion greater than the ionic radius of a potassium ion?
- AIonic radius always decreases with increasing atomic number.
- BPositive ions have smaller radii than negative ions.
- CThe potassium ion has more protons in its nucleus than the sulfide ion.
- DThe sulfide ion is doubly charged; the potassium ion is singly charged.
