A Hydrogen atom has one proton and one proton in it. There are no neutron in hydrogen atom. As a matter of fact, hydrogen is the only element whose atom does not have a neutron in it.

Hydrogen does have some isotopes with atoms that contain one or more neutrons in its atoms. The atom of most most common isotope of hydrogen called protium, which is really the common hydrogen, contains no neutron. The atom of a second isotope of hydrogen called deuterium or heavy oxygen contains 1 proton and 1 neutron. This isotope constitutes about 1 part out of 4000 to 6000 parts of normal oxygen.The atom of another isotope of hydrogen called tritium has 1 proton and 2 neutron. Tritium is a radioactive material and is used in making oh hydrogen bomb.

1 electron, 1 proton and no neutrons!!! Anyway, hydrogen has isotopes (which means same numbers of protons but different numbers of neutrons).....Hope the answer u hav already got is the  best!!!

In Hydrogen

Neutrons= 0

Protons= 1

Electrons= 1

In a Hydrogen atom there is 1 electron , 1 proton , but there is not any neutrons .

Number of energy levels that a Hydrogen atom have is only 1 .

There are isotopes of Hydrogen that do contain neutrons. For example, deuterium has one neutron and tritium has 2 neutrons.

A hydrogen atom contains 1 electron, 1 proton, and no neutrons based on the Periodic Table. The isotopes of the hydrogen atoms however, do contain neutrons. Deuterium as one neutron and tritium has two neutrons, based on the definition that an isotope an element with same number of protons but different number of neutrons.
