Answer:

See below.

Explanation:

A hydrogen atom has an atomic number of #1#.

So it's proton number will always be #1#.

A neutral hydrogen atom does not have any charge.

So it has the same amount of electrons as protons, which turns out to be also #1#.

A neutral hydrogen atom has an atomic mass of #~~1.00794 "amu" ~~ 1 "amu"#.

To find the amount of neutrons, we take the proton number and subtract it from the mass number.

#1-1=0#

So a neutral hydrogen atom has no neutrons.

In summary,

A hydrogen atom has

#1# proton
#1# electron
#0# neutrons

I hope that helps!
