The emission of a Beta particle has the effect of:

a change in mass of an electron emitted from the nucleus
decreasing mass by one unit
increasing mass by one unit
adding a proton to the nucleus
converting 1 neutron to 1 electron and 1 proton

all of they above

Explanation:

The answer is adding a proton to the nucleus.

Explanation:

The answer is adding proton to the nucleus.

Beta decay is radioactive decay in which a beta ray and a neutrino are emitted from an atomic nucleus.  

There are two types of beta decay: beta minus and beta plus.  

In beta plus decay, a proton is converted to a neutron, positron and an electron neutrino, so mass number does not change.

In beta minus decay (atomic number Z is increased by one) neutron is converted to a proton and an electron and an electron antineutrino.

For example, nuclear reaction:

²⁶Na → ²⁶Mg + e⁻(electron) + ve(electron antineutrino

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
