Answer:
+1
Explanation:
Let x be the missing value in the equation as shown below:
²²₁₁Na —> ²²₁₀Ne + ⁰ₓβ
The missing value (x) can be obtained as follow:
11 = 10 + x
Collect like terms
11 – 10 = x
1 = x
x = 1
Therefore, the missing value (x) is +1 and the balanced equation is:
²²₁₁Na —> ²²₁₀Ne + ⁰₁β
