I’m duty bound to say Hydrogen! It’s a remarkably useful gas that will be needed to make all manner of industrial processes and transport better for the environment

I think I might be addicted to oxygen. I just can’t seem to live without it.

oxygen – you just cant live without it. my second favorite would be helium. its always good for a laugh and great at parties very useful.

Helium. It makes your voice go squeaky if you breathe it, and it’s funny! The change in your voice is because sound travels at different speeds in different gases.

I like nitrogen. Our bodies need oxygen, but nitrogen makes up about 78% of the air we breathe.
We use liquid nitrogen at work and we have to be very careful that there’s good ventilation for when the liquid nitrogen turns to gas, because if the amount in the air gets too high it’s really bad for us. So why is it still my favourite? Because you can cool it down to make liquid nitrogen, and that’s really useful for experiments. -

I like them all because the planet needs them to function! Right now, though, I’m most interested in hydrogen. Did you know that hydrogen makes up 73 percent of the mass of the universe? Helium is another 25 percent and everything else (including all the oxygen in the universe) is only 2 percent all together!

Oxygen because I can’t live about it. Who will do all the amazing experiments and make fascinating discoveries 😉

Nitrogen – as chemists, my research group does a lot of reactions which don’t work if exposed to air or oxygen. Nitrogen is a cheap and easy to use gas which we use to displace air from our reaction containers.

I’d say Helium because it makes your voice sound funny. However, we are actually running out of it, as it is so light it can escape our atmosphere. This is important as it is also used in medical equipment.
