This Huge Table is a detailed periodic table that does not fit on most computer screens. However, in print with a small font, or in landscape mode, this table can be printed onto a single normal-sized paper (A4 or 8½ x 11"). For a printable version that uses less colored ink (and works without color), see this.

How to remember the first 20 elements easily
This method was made by Sanjith Sagar, a student of Glendale Academy International, Hyderabad, India. He's currently in Grade 10. He considered the first 20 elements and made various combinations to form words. All you have to do is remember the word sequence and you'll automatically get the table.

First thing he did was make various pairs of elements.
(Below is the short form of the elements. Remember it this way)
H
He
Li
Be
B|
C|
N|
O|
F|
Ne~
Na~
Mg]
Al]
Si^
P^
S^
Cl-
Ar-
K-
Ca
(The |,^,~,etc. Are the different groups in which the elements are classfied. Meaning B,C,N,O,F are one group.)


Consider the first group. H,He,Li,Be. Remember as it is. It's a nice ring to it which helps. One advise is remember it as the Full forms. Hydrogen, Helium, Lithium and Beryllium. End with -ium
Next group is B,C,N,O,F. All these are single letters. REMEMBER THEM LIKE A RUSSIAN NAME, BCNOF or remember it using the short forms because in this group all are alphabets not a combination like Be or Cl.
Next group is Ne,Na. Okay try reading it together. Sounds like Nina(NeNa) right?. So that's how you remember it
Next group is Mg,Al. Try reading this as well. Sounds like Migal(MgAl) right? Remember it this way
Next group is Si,P,S. We can make a proper word out of this. Sips(Si,P,S).
Next group is Cl,Ar,K. Make a word out of this. Clark(Cl,Ar,K).
And finally. Remember Ca as it is



The first 20 elements is very much required to do good in chemistry. The order mentioned above is the ascending order of atomic number of elements




So it is:
The ring, BCNOF, Nina(NeNa), Migal(Mg,Al), Sips(Si,P,S), Clark(Cl,Ar,K) and Ca

Touchspin's Interactive Periodic Table Elements 103-118 don't have the same atomic [weight] represented everywhere.
Elements with [atomic weights in brackets] are rounded from their actual atomic weights.
Metals, metalloids, and nonmetals have no one definition.
