Use the equation to complete the activity. 2198621986 Rn + Beta→ 2198521985 As The nuclear equation shows a form of radon into astatine and a beta particle. In one to two sentences, explain whether or not the reaction is balanced. (1 point) Responses mass number is zero, and it is a neutron mass number is zero, and it is a neutron mass number is zero, it is a proton mass number is zero, it is a proton mass number is zero, it is a gamma. mass number is zero, it is a gamma. mass of beta is zero, and it is an electron

1 answer

The reaction is balanced because the sum of mass numbers on both sides of the equation is equal, indicating the conservation of mass in the nuclear reaction.
