Vedclass · Answer

(A) The notation ${ }_{Z} X^{A}$ represents an atom where $Z$ is the atomic number and $A$ is the mass number.For ${ }_{11} Na^{23}$,the atomic number $Z = 11$ and the mass number $A = 23$.The number of protons in the nucleus is equal to the atomic number $Z$,so protons = $11$.The number of neutrons is given by $N = A - Z = 23 - 11 = 12$.The nucleus of an atom contains only protons and neutrons; it does not contain electrons.Therefore,the number of electrons in the nucleus is $0$.Thus,the number of protons,neutrons,and electrons in the nucleus are $11, 12, 0$ respectively.

In the nucleus of ${ }_{11} Na^{23}$,the number of protons,neutrons and electrons are
