Question

The emission of a Beta particle has the effect of...? A. Decreasing mass by one unit /B.Increasing mass by one unit / C. - No change in mass /D.- Adding a proton to the nucleus / E.Adding a proton of zero mass to the nucleus

Answer 1

Answer: The correct answer is Option C.

Explanation:

Emission of beta particle occurs when an atom undergoes beta decay process.

Beta decay is defined as the process in which beta particle is emitted. In this process, a neutron gets converted to a proton and an electron.  The electron released is known as beta particle.

The equation representing beta decay process follows:

$_Z^A\textrm{X}\rightarrow _{Z+1}^A\textrm{Y}+_{-1}^0\beta$

From the above equation, the mass number of the nucleus formed does not get changed. The mass number remains the same which is 'A'

Thus, the correct answer is Option C.

Answer 2

The emission of a beta particle has the effect of : C. No change in mass

basically, beta particle has a very very little mass compared to the proton and  neutrons, so  little to the point that it never considered as a change in mass. But it does decreases the charge of atom

hope this helps
