#""_17^40Cl->""_18^40Ar+""_(-1)^0e^-#

Explanation:

In a beta-minus decay, an atom converts one of its neutrons into a proton, while releasing an electron and an antineutrino in the process.

In any nuclear equation, the total mass on both sides should be equal, and also the total numbers of protons should add up to be equal.

So here, the equation will be:

#""_17^40Cl->""_18^40Ar+""_(-1)^0e^-#
