Chapter 17, Problem 16TE

To determine

The reason as to why water is not classified as an element.

Answer to Problem 16TE

The water is a molecule and can be broken into elements. So, it is not classified as an element.

Explanation of Solution

The substance which cannot be broken into a simpler substance by chemical means is termed as an element.

The elements are arranged in the periodic table.

The water is made up of oxygen and hydrogen. When two atoms of hydrogen element combine with one atom of oxygen element, one water molecule is formed.

The water molecule can be broken into simple atoms by chemical reactions.

The formula of water is ${\text{H}}_2\text{O}$

So, it is a molecule, not an element.

Conclusion:

The water is a molecule and can be broken into elements. So, it is not classified as an element.
