Answer 1

A) Hydrogen
Plutonium is used in nuclear reactors, and Uranium in nuclear fission.

Answer 2

Hydrogen

Step-by-step explanation:

Hydrogen is often used in fusion reactions

4 ¹₁H --> ⁴₂He + 2⁰₁e

Four hydrogen atoms undergo fusion reaction to form helium and 25 MeV( mega electron volt) of energy. Fusion reaction also occurs with isotopes of hydrogen such as deuterium and tritium.

²₁H + ²₁H --> ⁴₂He

²₁H + ³₁H --> ⁴₂He + ¹₀n
