Hydrogen (the isotope 1H) is the most simple atom; and the mass is only approx. 1.
No, hydrogen does not have a neutron in its atomic structure.
Both are isotopes of hydrogen with 1 proton and 1 electron. H-1 (protium) has 0 neutron whereas H-2 (deuterium) has 1 neutron
Depending on the isotope it could be 0,1 or 2. Usually it is 0.
Because it has only 1 proton, 1 electron and 0 neutron in its atom.
No, a hydrogen atom does not have a neutron in its nucleus. A hydrogen atom consists of only one proton in its nucleus.
Hydrogen-1, (there is a trace of hydrogen-2 (deuterium) found in nature, and hydrogen-3 is an artificial isotope)
Three isotopes. All have one proton and one electron. Protium has 0 neutron, Deuterium has 1 neutron, Tritium has 2 neutrons.
it has a neutron extra
Isotopes (of hydrogen) differ in the number of neutrons in the nucleus of the atoms.
A neutron, although this is not always the case as there are hydrogen atoms with neutrons, but hydrogen atoms are the only one which are able to not have a neutron.
There is one proton, one electron in hydrogen. The number of neutrons depends on the isotope of hydrogen. Hydrogen has three isotopes: protium, deuterium and tritium with 0, 1 and 2 neutrons respectively.
Hydrogen does not have any neutrons unless it is the isotope deuterium ( 1 neutron) or tritium (2 neutrons)
