A) the mass number decreases by one.

B) the mass number increases by one.

C) the atomic number increases by one.

D) the atomic number remains the same.

Answer 1

When a beta particle is released from the nucleus of an atom:


the number of electrons in the atom decreases by one

the number of electrons in the atom increases by one as the beta particle leaves the nucleus and joins the valence electrons

the mass number of the atom remains the same

the mass number of the atom decreases

Answer 2

So the answer is A ?

Answer 3

yes
