Answer 1

Answer:

The main aim of classifying metals is the need to make the study of elements easier.

Atomic number is the fundamental property.

The Modern Periodic law states the 'Properties of elements are a periodic function of their atomic number.'

Metals on the left side.

Non metals on the right side.

Metalloids on the left of non metals in a zig-zag form.
