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

No change in mass

Explanation:

Beta-emission: In this process, a neutron gets converted into a proton and an electron. The electron is referred to as a beta-particle. The beta particle released carries a charge of -1 unit and has negligible mass.

General representation of an element is given as:

Z= Atomic number

A = mass number

X = chemical symbol of element

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.
