Question

Pair the following species that contain the same num-
ber of electrons: Ar, Sn4+, F, Fe3+, P3-, V, Ag+, N3-.
4+

Answer 1

Based on the electronic configuration;

• Sn4+ and Ag+ have 46 electrons each
• Ar and P3- have 18 electrons each
• Fe3+ and V has 23 electrons each

What species have the same number of electrons?

• Electrons in neutral atoms are equal to the number of protons in that atom.

However, atoms can lose or gain electrons to form ions.

• Metals lose electrons to have a positive charge.
• Non-metals gain electrons to have a negative charge.

Ar contains 18 electrons

Sn4+ has lost 4 electrons to then have 46 electrons

F has 9 electrons

Fe3+ has lost 3electrons to have 23 electrons

P3- has gained 3 electrons to have 18 electrons

V has 23 electrons

Ag+ has lost one electron to have 46 electrons

N3- has gained three electrons to have 10 electrons

Therefore, based on the electronic configuration:

• Sn4+ and Ag+ have 46 electrons each
• Ar and P3- have 18 electrons each
• Fe3+ and V has 23 electrons each
