Answer:
radius of a nucleus is 5.784× meters
Step-by-step explanation:
Since radius of a nucleus is measured by the formula
R =
Where is the average radius of a nucleus. This radius varies with the size of nucleons.
In this formula A = number of nucleons = (Number of protons + neutrons)
For element Cd number of nucleons = 112
and = 1.2×
Now we put these values in the given formula
R =
=
= 5.784× meters
Therefore, radius of a nucleus is 5.784× meters
