Question

The most abundant element in the Sun is .

Answer 1

Hydrogen is the most abundant element in the sun.

Answer 2

Answer: Most abundant element in the Sun is Hydrogen.

Explanation:

Sun is the only star in our Solar system. The element which is present in abundance in Sun is hydrogen element.

Hydrogen element undergoes fusion process which leads to the formation of helium atom. This process results in the release of tons of energy in the form of heat.

The equations for the fusion process of hydrogen element is given by:

$_1^1\textrm{H}+_1^1\textrm{H}\rightarrow 1^2\textrm{H}+_{+1}^0\textrm{e}+\text{energy}\\\\_1^2\textrm{H}+_1^1\textrm{H}\rightarrow 2^3\textrm{He}+\text{energy}\\\\_2^3\textrm{He}+_1^1\textrm{H}\rightarrow _2^4\textrm{He}+_{+1}^0\textrm{e}+\text{energy}$

Overall reaction for the above series of reactions is given by:

$4_1^1\textrm{H}\rightarrow _2^4\textrm{He}+2_{+1}^0\textrm{e}+\text{energy}$

Hence, most abundant element in the Sun is Hydrogen.
