Question

We classify elements to understand physical and ________ properties.

Answer 1

There are more than 110 elements. Without classifying these elements we are unable to study their behavior. So we classify them.

The following are advantages of classification:

1. To study the elements in a systematic manner.

2. To correlate the physical and chemical properties of elements.

3. To know the type of different compounds that different elements can form.

So the correct answer is chemical.
