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
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.
Isotopes (of hydrogen) differ in the number of neutrons in the nucleus of the atoms.
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)
