- B \({ }_{24} \mathrm{Cr}_{{ }_{30}} \mathrm{Zn}\)
- C \({ }_{19} \mathrm{~K},{ }_{33} \mathrm{As}\)
- D \({ }_{29} \mathrm{Cu}_{{ }_{30}} \mathrm{Zn}\)
Answer & Solution
Correct Answer
(A) \({ }_{24} \mathrm{Cr}_{{ }_{33}} \mathrm{As}\)
Step-by-step Solution
Detailed explanation
Given, mass number of \(X=52\) Mass number of \(Z=75\) Suppose, number of protons in \(X=a\) \(\therefore\) Number of neutrons \(=0.166 a+a=1.166 a\) As we know that, Mass number \(=\) Number of proton + Number of neutron…
