Options
- Apositron
- Belectron
- Cneutron
- Dproton
Correct answer
D. proton
Step-by-step solution
The nuclear reaction can be written as: ¹⁴₇ N + ⁴₂ He ¹⁷₈ O + ^ A _ Z X Applying the law of conservation of mass number: 14 + 4 = 17 + A A = 1 Applying the law of conservation of atomic number: 7 + 2 = 8 + Z Z = 1 The particle with mass number 1 and atomic number 1 is a proton ( ¹₁ p ).
