Answer:
radius of a [tex]^{112}Cd_{12}[/tex] nucleus is 5.784×[tex]10^{-15}[/tex] meters
Step-by-step explanation:
Since radius of a nucleus is measured by the formula
R = [tex]R_{0}(A)^{\frac{1}{3} }[/tex]
Where [tex]R_{0}[/tex] 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 [tex]R_{0}[/tex] = 1.2×[tex]10^{-15}[/tex]
Now we put these values in the given formula
R = [tex]1.2\times 10^{-15}\times(112)^{\frac{1}{3}}[/tex]
=[tex]1.2\times 10^{-15}\times4.82[/tex]
= 5.784×[tex]10^{-15}[/tex] meters
Therefore, radius of a [tex]^{112}Cd_{12}[/tex] nucleus is 5.784×[tex]10^{-15}[/tex] meters
