The emission of a Beta particle has the effect of?

Decreasing mass by one unit

Increasing mass by one unit

No change in mass

Adding a proton to the nucleus

Adding a proton of zero mass to the nucleus

A beta particle is similar to an electron with essentially no mass and has a negative charge. The atomic number of a neutral atom is equal to the number of protons and the number of electrons of the atom. The atomic weight meanwhile is equal to the sum of the number of protons and number of neutrons. Hence when beta particle is emitted, the effect is E. Adding a proton of zero mass to the nucleus
