there is any trik to learn d- block element(any one have then told me)

Hi Yogesh,

 

There is no such shortcut to learn d-block element. Yes, you can make your own Mnemonic to learn the table. The first series of d-block extremely important and you should definitely learn it and the coinage metal group consisting of copper, silver and gold also.

 

Hope it helps.

Good Luck!
