water* not whatever!

Привет! Извините, я не могу это сказать в русском: I looked up the chemistry and it is not that hard. All atoms are made up of 3 things, protons, electrons, and neutrons. The number of protons determines what element the atom is and when atoms bond together into molecules, individual atoms gain and lose electrons and this is the hard part in understanding chemistry.

Luckily, the chemistry in this situation is very easy because it is just neutrons. Atoms also have neutrons, hydrogen can have up from 1 to 3 neutrons. Each one of these is a different isotope of hydrogen. The one most common on Earth just has one neutron but the one found on the comet has 2 neutrons, that is why it is heavier.

The chemical formula for whatever as I am sure you know is H2O so every one oxygen atom has 2 hydrogen atoms. The water found on the comet had hydrogen atoms that contained 2 neutrons instead of one. That is all.

Спасибо большое!
