we know the final nuclues formed after beta- decay has one proton more than initial nucleus and electron and antineutrino is emmited from nucleus then tell me the no. of electrons in nucleus formed after decay

Daer Minku,

he antineutrino (or anti-neutrino) is a lepton, an antimatter particle, the counterpart to the neutrino.

Actually, there are three distinct antineutrinos, called types, or flavors: electron antineutrino (symbol ¯ν_e), muon antineutrino (symbol ¯ν_μ), and tau antineutrino (symbol ¯ν_τ).

BEST OF LUCK..!!!!
