Answer to Problem 54A

There are only about 100 different elements but more than 1000 different atoms. This is because of the existence of isotopes due to which the number of neutrons differs in each of the isotopes.

Explanation of Solution

An atom is the smallest component of an element which is maintaining its identity during a chemical reaction.

More than 1000 different atoms are existing.

But the number of elements is only above 100.

This difference is due to the existence of isotopes.

Atoms that have various numbers of neutrons and different masses but the same number of protons are called isotopes.

The isotopes differ in the number of neutrons so different atoms exist due to this reason.
