QUESTION:

Compare the atomic size of the following two magnesium isotopes: \({ }^{24} \mathrm{Mg}\) and \({ }^{26} \mathrm{Mg}\).

ANSWER:

Step 1 of 2

Here, we are asked to compare the atomic size of magnesium isotopes:  and .

Isotopes are the atoms that have the same atomic number, that is the same number of protons but a different number of neutrons. Since there is a difference in the number of neutrons, atoms may exhibit different physical properties. We represent isotopes as :

        

        or

        X-A

Where ‘A’ represents mass number

         ‘Z’ represents Atomic number

         ‘X’ represents the chemical element.
