Vedclass · Answer

(C) For an element represented as $_{Z}^{A}Y$,the number of protons is equal to the atomic number $(Z)$.In the given element $_{89}^{231}Y$,the atomic number $Z = 89$,so the number of protons is $89$.Since the atom is neutral,the number of electrons is equal to the number of protons,which is $89$.The number of neutrons is calculated as $A - Z = 231 - 89 = 142$.Therefore,the number of protons,neutrons,and electrons are $89, 142, 89$ respectively.

The number of protons,neutrons,and electrons in the element $_{89}^{231}Y$ is:
