oxygen
There are 32 grams of sulfur in a mole of that element. There are also 32 grams of oxygen in one mole of oxygen as it is found in its natural state (O2).
Hydrogen is a non metal element. Atomic number of it is 1.
Hydrogen is a gas. atomic number of H is 1.
Hydrogen is not a mixture at all. It is an element and therefore a pure substance.
The second element in group 1 is beryllium, with an atomic number of 4.
The star Arcturus is not a biotic factor of a niche. This answer may surprise you but it is a true answer.The thing is that when you ask a question in the negative (What/Which is not) two things happen:-1) It is almost impossible to understand what you are actuality wanting to know.2) That apart from the things that ARE a biotic factor of a niche, EVERYTHING else the universe is a true answer.
