Isn't there a fourth hydrogen called protium, or hydrogen-1 as well?

[MarkRosengarten]

@koppen123 H-1 is protium, H-2 is deuterium and H-3 is tritium.

THANKS ALOT this video was very helpfill to me

[MySpykee]

Very interesting, and 'classical'. There are some questions I have not been able to get answers to (or if i do get answers they are so jargon riddled as to be worse than useless).

1) I am lead to believe neutrons stabilise Protons from flying apart due to their like charges. But Neutrons don't have charges, so they should hang together due to nuclear attractions alone. Why can't you have groups of neutrons as stable nuclei?

2) How do I make sense of the NOT 1:1 ratio of protons:neutrons?

you're the best mark! if i have you as my chem teacher i would probzably had pass 17years ago lolz. Now i'm back to school and studying from you

[abhinavjoshi14914914]

But 7000 protons will have mass of 1007....but a charge of 1000 lol

Thank you so much!!!
