Yes. It is necessary to memorise it because the if you remember these elements then from the trends you can easily find out their physical and chemical properties.
 
There are three easy ways to remember periodic table:

1. Always carry a printout or prepare flash cards of the periodic table so you can go through it in your free time.

2. Breakdown the periodic table into smaller sections and study each section separately.

3. Create your own Mnemonics.

Example:

Period 1 – H, He

Mnemonics – HHello

 

Period 2 – Li, Be, B, C, N, O, F, Ne
Mnemonics – Little Betty Became Charlie’s Number One Friend and Neighbour.

 

Period 3 – Na, Mg, Al, Si, P, S, Cl, Ar
Mnemonics – Naughty Maggie Always Sings Perfect Song “Climbing Around”.
