Mg+2and F-ions differ in which of the following fundamental particles?...
Explanation:
Mg2+ ion is formed by the loss of 2 electrons from the outermost shell of a magnesium atom. Therefore, it has 12 protons, 10 electrons, and 12 neutrons. F- ion is formed by the gain of 1 electron in the outermost shell of a fluorine atom. Therefore, it has 9 protons, 10 electrons, and 10 neutrons.

Differences between Mg2+ and F- ions:

Protons: Mg2+ ion has 12 protons whereas F- ion has 9 protons.

Electrons: Mg2+ ion has 10 electrons whereas F- ion has 10 electrons.

Neutrons: Both ions have different numbers of neutrons. Mg2+ ion has 12 neutrons whereas F- ion has 10 neutrons.

Conclusion: Therefore, the fundamental particles that differ between Mg2+ and F- ions are protons and neutrons.
