Which of following reaction is correct ? (Where symbols have their usual meanings)

(Shift - I Memory Based)

a

\(n\to p+{e}^{−}+\nu\)

b

\(n\to p+{e}^{+}+\nu\)

c

\(n\to p+{e}^{+}+\nu\)

d

\(n\to p+{e}^{−}+\nu\)

✓ Correct answer: d)

\(n\to p+{e}^{−}+\nu\)

Explanation

It is the equation of neutron (n) decays into a proton (p), in which an electron (e⁻) is emitted, and an antineutrino is emitted to conserve lepton number.
