Oxygen
This gas is oxygen.
Oxygen is the only element with 8 protons.

Oxygen
The number of protons and neutrons in an atom is equal to its atomic mass. Since the atomic mass of this gas atom is 16 and it has 8 neutrons, the remaining mass (16-8=8) must be the protons in the nucleus. Therefore, this gas atom has 8 protons.
That would be a gas with the Atomic 8 and mass number of 16 - Oxygen
You mean protons, not patrons.The answer is Oxygen and more specially: neutrons + protons ---> 16O
An atom with 8 protons will have an atomic number of 8. Checking the periodic table, we see this element is oxygen. The isotope of oxygen with 8 neutrons is 16O.
Oxygen.
Oxygen. The Elements Atomic Number tells you the number of protons and it's amu is generally the weight of all of the averaged isotopes so since it is nearly 16 (not all O's have 8 neutrons) it is Oxygen.
ok N has 14 protons and electrons. C has 12 protons and electrons. O has 16 protons and electrons. nitrogen gas is not N, it is N2, which means 28 protons and electrons. C and O added up is also 28.
In 1 mole of NO2 gas, there are a total of 9 moles of protons. This is because NO2 has 1 nitrogen atom and 2 oxygen atoms, which contain a total of 9 protons (7 protons from nitrogen and 2 protons from each oxygen).
