$_{22}^{24} M g$ and $_{22}^{26} M g$ are symbols of two isotopes of magnesium.
Compare the atoms of these isotopes with respect to:
1) composition of their nuclei
2) their electronic configuration

Open in App

Solution

Atomic number(no. of protons) number of nuetrons Atomic mass
1. 22 24 46
2. 22 26 48
so their nucleus composition is different and also atomic mass differs
But their configuration is same due presence of same number of electrons .
