Answer is: this is reduction.
Reduction half reaction: Sn⁴⁺(aq) + 2e⁻ → Sn²⁺(aq).
Reduction is lowering of oxidation number because ions or element gain electrons and oxidation number is decreased (in this example from +4 to +2).
In oxido-reduction reaction, at least one element lose and one element gain electrons.
Oxidation reaction is increasing of oxidation number of atom, because element lost electrons in chemical reaction.

Answer from: Maddy1212

Reduction term describes this reaction

Sn⁴⁺(aq) + 2e⁻ ⇒ Sn²⁺(aq)

Further explanation

Reduction oxidation reaction is a chemical reaction in which there are changes in oxidation numbers

The general formula for determining oxidation numbers:

1. Single element atomic oxidation = 0. For example Ar, Mg, Cu, Fe, N₂, O₂, etc. = 0

Group IA (Li, Na, K, Rb, Cs, and Fr) +1

Group IIA (Be, Mg, Ca, Sr and Ba) +2

H atoms in compounds = +1, except metal hydride compounds (Hydrogens that bind to groups IA or IIA) oxidation numbers H = -1, for example LiH, MgH₂, etc.

2. O atoms in compounds = -2, except OF2 = + 2 and at peroxide (Na₂O₂, BaO₂) = -1 and superoxide, for example KO₂ = -1/2. 3. The oxidation number in the uncharged compound = 0,

we complete the answer choices

Which term best describes this reaction?

(1) ionization (3) oxidation

(2) neutralization (4) reduction

On reaction

Sn⁴⁺(aq) + 2e⁻ ⇒ Sn²⁺(aq)

the Sn atom experiences an reduction reaction (decrease in oxidation number) from 4+ to 2+
