How many neutrons does a standard hydrogen atom have in its nucleus

There will be 0 neutron in standard hydrogen atom

Explanation:

We know that standard hydrogen is denoted by

Means mass number of hydrogen is 1 and atomic number is also 1

So mass number A = 1

And atomic ,that is number of proton number Z = 1

We have to find the number of electrons in standard hydrogen atom

We know that mass number is given by

Mass number = number of proton + number of neutron

1 = 1 + number of neutron

So number of neutron = 1 -1 0

this means that the temperature of both substances will be equal

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
