Use the equation to complete the activity.

21986
Rn + Beta→21985
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.

mass of beta is zero, and it is an electron
mass of beta is zero, and it is an electron

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 number is zero, and it is a neutron

The reaction is balanced because the total atomic numbers and total mass numbers on both sides of the equation are equal, indicating that mass and charge are conserved in the reaction.

whats the answer

The correct response is: The reaction is balanced because the total atomic numbers and total mass numbers on both sides of the equation are equal, indicating that mass and charge are conserved in the reaction.
