It does have Chemical Information

Click the element you want, and scroll down to "Chemical Data", click HTML.
Under Physical Information, it gives you what you need to know:
Atomic Number 6
Relative Atomic Mass (12C=12.000) 12.011

That is from Carbon.

The atomic number relates to the number of electrons and protons both, the Relative Atomic Mass is the Number of Protons plus the number of Neutrons.

That gives you enough information to draw the nucleus, in this case there are 6 protons and 6.011 Neutrons, although 6 Neutrons would generally be accepted at the level you`re doing. [img]smile.gif[/img]

The only complication is the electron shells: just remember the pattern 2,8,8,16 ; that should be as far as you need go [img]smile.gif[/img]

EDIT: Ok, to quote from my science text book:
The total number of electrons allowed in a shell n and all those before it, is 2n².

Thus,

Shell Number (n) ..... Maximum Number of Electrons (2n²).
1 ..... 2
2 ..... 8
3 ..... 18
4 ..... 32
etc etc

Here the book starts getting very... wierd.
It gives a diagram of a Chlorine atom, with 2,8,7.

But from the table it gives, it should be 2,6,8 ... I have always learned 2,8,8,16; so er... ignore 2n²
