The question is incomplete, here is the complete question:
Two atoms interact with each other as shown by the equation. Complete the equation by filling in the missing parts.
[tex]_1^2\textrm{H}+_1^2\textrm{H}\rightarrow _Z^A\textrm{X}+_0^1\textrm{n}[/tex]
Answer: The isotopic symbol of the missing part is [tex]_{2}^{3}\textrm{He}[/tex]
Explanation:
In a nuclear reaction, the total mass and total atomic number remains the same.
For the given fusion reaction:
[tex]_1^2\textrm{H}+_1^2\textrm{H}\rightarrow _Z^A\textrm{X}+_0^1\textrm{n}[/tex]
Total mass on reactant side = total mass on product side
2 + 2 = A + 1
A = 3
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 [tex]_{2}^{3}\textrm{He}[/tex]
Answers:
Top: 3
middle: He
Bottom: 2
