What gas has 8 protons and 8 neutrons?

Answer 1

Oxygen-16.

Well, we use the number of protons and number of neutrons and add them up to give us the average atomic mass.

#8+8=16#

Therefore the average atomic mass is #16# g/mol. If we look at a Periodic Table, we can see that Oxygen in the 16th period, 2nd row, has this mass.

In addition, at room temperature, oxygen's state is gaseous.

Now there is something called "isotopes", in which the atom of the same element, has an altered configuration - different number of neutrons. O-16 is the most common isotope of oxygen.

Thus, we can conclude that the gas you are specifying is oxygen. To be specific, oxygen-16.

Hope this helps :)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
