Free neutron changes into proton with the emission of

Correct answer: B. Electron

  • A. Neutrino
  • B. Electron
  • C. Both a and b
  • D. Meson

Explanation

A free neutron can change into a proton with the emission of an electron. This process is known as beta decay, specifically beta-minus decay. In this decay, a neutron is transformed into a proton, and an electron (beta particle) and an antineutrino are emitted. So, option (b) Electron is the correct answer

About Atomic Structure

Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
