Hi !
It's very easy to remember the Mass numbers of the first 30 elements.
Now the Atomic Numbers of the elements are in the right order,so we have no problem with it.
Coming to the Mass numbers you can see that most of the Mass numbers are twice it's Atomic number.Only for some elements we have to add one.So you will have to remember to which one should be added.
Now from the 21st element the problem begins.For some elements you have to add 3,some 4 and so on.Therefore you will have to byheart the Mass numbers of the last 10 elements.
Hope it helps...............
