Chapter 17, Problem 23R

To determine

To Explain: The molecule which is composed of two atoms of the same element

Explanation of Solution

Introduction:

Diatomic molecules are basically of two types. One is homonuclear and other is heteronuclear.

If the atoms of diatomic molecule are same then it is called homonuclear diatomic molecule. For example: hydrogen

If the atoms of diatomic molecules are different then it is heteronuclear diatomic molecule such as carbon monoxide or nitric oxide

Conclusion:

Thus, the molecule which is composed of two atoms of the same element is called diatomic molecule and in particular it is known as homonuclear.
