When two negative beta particles are emitted from a nucleus then the mass number _____?

جب ایک نیوکلئس سے دو منفی بیٹا ذرات خارج ہوتے ہیں تو ماس نمبر _____؟
Explanation
  • The emission of two negative beta particles (electrons) does not affect the mass number since it involves the conversion of neutrons to protons without changing the total number of nucleons.
  • The mass number remains unchanged because the emission of beta particles only affects the atomic number, not the mass number.
