Hydrogen does not have any neutrons unless it is the isotope deuterium ( 1 neutron) or tritium (2 neutrons)
I'm pretty sure its a hydrogen atom
One neutron per atom of hydrogen.
A hydrogen atom has the smallest diameter because there is only one proton and neutron.
It would be Deuterium, also called Heavy Hydrogen.
You are an atom of heavy hydrogen, or deuterium. Most hydrogen has one proton and one electron, which form a neutral atom. But once in a while, a neutron will stick to the proton, and then the atom, which is still hydrogen (it has just the one proton) will be about twice as massive as "regular" or "common" hydrogen. It is another isotope of hydrogen called heavy hydrogen or deuterium.
Hydrogen H+ ion is (i.s.o. 'can be thought of as ...) one proton.
The only element that does not have a neutron in its nucleus is hydrogen-1, which consists of one proton and one electron.
If hydrogen had a neutron, it wouldn't be hydrogen; it would be deuterium. If it had two neutrons, it would be tritium.
The "NUMBER" (#) of Protons in an Atom of Hydrogen is one (1). The number of protons is what makes a specific element that element. Hydrogen always has one proton no matter what. If someone says that a hydrogen atom has two protons(they are incorrect), it is no longer hydrogen; it is the element Helium.
Deuteriums emision spectrum either is like hydrogen http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch6/bohr.html or like http://en.wikipedia.org/wiki/Image:Deuterium_lamp_1.png
Neutons, located in the nucleus. Protons, also located the the nucleus but Elecrons, there is further study.
None. A hydrogen atom has one proton and one electron (no neutron). Removing the electron leads to just a proton, no electrons.
