>> As hydrogen is the simplest, lightest atom with R.A.M. of 1, <<

This is the first time you use the abbreviation R.A.M. (which may be better shown as RAM - I think there's an EG standard about this ) so could you either footnote the first use of Relative Atomic Mass (Abbreviated to RAM) or footnote this abbreviation? I (and all the other chemists) know what you mean, but it isn't immediately apparent to the lay reader.

>> same number of particles as is found in 12.000 grams of carbon-12. That number of particles is known as Avogadro's Constant (NA), which is roughly 6.02x1023. A mole of carbon atoms is 6.02x1023 <<

Just as a matter of consistency, can you show the same rounding of decimal points throughout? (Earlier Avogadro's constant is shown as 6.022x10^23.)

Nice entry! Took me back to my school days!

I've inserted (R.A.M.) in brackets at the point of first use.

I don't see the need to usequote Avogadro's Constant to the same number of decimal places each time as I've used the word 'roughly', and it looks pedantic to beek writing 6.022 X 10

Good one BigAL,
