Answer:
¹⁴₇N + ⁴₂He → ¹⁷ ₈O + ¹₁p
Explanation:
¹⁴₇N represents the isotope of nitrogen-14, where the superscript 14 to the left of the chemical symbol of the element is the mass number (number of protons and neutrons) and the subscripst 7 is the atomic number (number of protons).
α is used to represent alpha particles. Alpha particles are nucleus of helium, ⁴₂He: mass number 4, atomic number 2,
The expression ¹⁴₇N + α represents a nuclear reaction: the nucleus of the isotope of nitrogen-14 (¹⁴₇N) is hit by α-particles ( ⁴₂He).
As result, the nucleus of ¹⁴₇N absorbs 1 proton, increasing its atomic number and mass number in 1, becoming ¹⁷ ₈O. In this process, also one proton is produced.
The total reaction is represented by ¹⁴₇N + ⁴₂He → ¹⁷ ₈O + ¹₁p, where you can verify the mass balance:
Mass numbers: 14 + 4 = 17 + 1 = 18.
Number of protons: 7 + 2 = 8 + 1 = 9.
