A) Z neutrons and A -Z protons
B) Z protons and A-Z neutrons
C) Z protons and A neutrons
D) A protons and Z-A neutrons

Solution :
| \[_{Z}{{X}^{A}}\] has number of protons \[=Z\] and number of neutrons \[=A-Z\] |
| Where A is the total number of protons and neutrons i.e., \[A=Z+AL\] |
| Note: The proton is nothing but the nucleus of hydrogen atom i.e., a hydrogen atom from which the single orbital electron has been removed. |
