Hello,

What are Elements?

Elements are a group of the Periodic Table that shares common valence electron structures. They are arranged in order of increasing Atomic Number.

Now back to the question:-

In modern periodic table they are classified into three parts- metals, non-metals and metalloids.

Metals- Metals are those elements which donate electrons. Ex- Na, K, Rb, Mg, Ca, etc.

Non-metals- Non-metals are those elements which accept electrons. Ex- N, O, F, Cl, etc .

Metalloids- Metalloids are those elements which show property of both metals and non-metals. Ex- B, Si, Ge, etc.

Hope it helps...
