Question

In radioactivity, Carbon-14 decays by emitting a _____________________.
1. Beta particle
2. Alpha particle
3. Gamma particle
4. Nuclear & Carbon particle

Answer 1

Correct Answer - Option 1 : Beta particle

The correct answer is Option(1).i.e.Beta particle.    

• In radioactivity, Carbon-14 decays by throw down a beta particle. 
• Beta-decay: 
  • A beta particle has a  -1 charge & it is an electron that emerged from the nucleus but not from the shells of electrons. 
  • We can introduce the beta particles as -10e. 
  • The conversion of the neutron into a proton is the net effect of beta particle emission on a nucleus. 
  • The number of protons increases by one, the atomic number also rise up by one, although the overall mass number stays the same. 
  • As is the sum of the mass numbers, the sum of the atomic numbers is the same on the equation's both sides.
• (Note: the electron is represented an “atomic number” of –1, equal to its charge.)
• Emission of Beta-decay: 
  • Carbon-14 decays by throw down a beta particle. 
  • For Example -    ¹⁴C₆ →  ¹⁴N₇ + ⁰e_-1
