Question

Which type of nuclear reaction involves combining light elements into a heavier element, with a resultant release of great amounts of energy?
Question 14 options:

Combustion

Fusion

Fission

Radioactivity

Answer 1

Answer: Fusion

Explanation:

Combustion is a chemical reaction in which hydrocarbons are burnt in the presence of oxygen to give carbon dioxide and water.

Nuclear fusion is a process which involves the conversion of two small nuclei to form a heavy nuclei along with release of energy.

$_{94}^{239}\textrm{Pu}+_2^4\textrm{He}\rightarrow _{96}^{242}\textrm{Cm}+_0^\textrm{n}$

Nuclear fission is a process which involves the conversion of a heavier nuclei into two or more small and stable nuclei along with the release of energy.

$_{92}^{235}\textrm{U}+_0^1\textrm{n}\rightarrow _{36}^{91}\textrm{Kr}+_{56}^{142}\textrm{Ba}+_{0}^{1}\textrm{n}$

Answer 2

Answer: Fusion

Explanation: Fusion is a nuclear reaction in which light elements are combined into a heavier element, resulting in the release of great amounts of energy
