The missing element : ₇¹⁴N
Further explanation
Given
Reaction
₆¹⁴C ⇒X + ₋₁⁰e
Required
The missing element
Solution
Radioactivity is the process of unstable isotopes to stable isotopes by decay, by emitting certain particles,
- alpha α particles ₂He⁴
- beta β ₋₁e⁰ particles
- gamma particles ₀γ⁰
- positron particles ₁e⁰
- neutron ₀n¹
In a decay reaction, the sum of the mass number and atomic number before and after the decay is the same.
The element X :
Atomic number = 6 + 1 =7
Mass number = 14 + 0 = 14
