Explanation:
Monatomic ions:
These ions consist of only one atom. If they have more than one atom then they are poly atomic ions.
Examples of Mono Atomic ions:
Part A:
For P:
Phosphorous (P) has 15 electrons so it require 3 more electrons to stabilize itself.
Charge is
Full ground-state electron configuration of the mono atomic ion:
Part B:
For Mg:
Magnesium (Mg) has 12 electrons so it requires 2 electrons to lose to achieve stable configuration.
Charge is
Full ground-state electron configuration of the mono atomic ion:
Part C:
For Se:
Selenium (Se) has 34 electrons and requires two electrons to be stable.
Charge is
Full ground-state electron configuration of the mono atomic ion:
