Two atoms interact with each other as shown by the equation. Complete the equation by filling in the missing parts.

$_1^2\textrm{H}+_1^2\textrm{H}\rightarrow _Z^A\textrm{X}+_0^1\textrm{n}$

Answer: The isotopic symbol of the missing part is $_{2}^{3}\textrm{He}$

Explanation:

In a nuclear reaction, the total mass and total atomic number remains the same.

For the given fusion reaction:

$_1^2\textrm{H}+_1^2\textrm{H}\rightarrow _Z^A\textrm{X}+_0^1\textrm{n}$

• To calculate A:

Total mass on reactant side = total mass on product side

2 + 2 = A + 1

A = 3

• To calculate Z:

Total atomic number on reactant side = total atomic number on product side

1 + 1 = Z

Z = 2

Hence, the isotopic symbol of the missing part is $_{2}^{3}\textrm{He}$
