No electrons are in the nucleus. the nucleus consists of a proton for normal hydrogen, a proton and neutron for deuterium and a proton and two neutrons for tritium. Deuterium and tritium are isotopes of hydrogen.
Tritium (Hydrogen-3, H3, T) has 1 Proton, 2 Neutrons, and 1 Electron.
Tritium is 3H, so it has one proton, one electron (in the non-ionized state) and two neutrons.
There are 77 Neutrons in the nucleus of one atom of Xenon
A Xenon neutron has between 70 to 82 neutrons.
Tritium [note correct spelling] has one proton and two neutrons per atom.
All hydrogen atoms, regardless of the number of neutrons in its isotope (zero neutrons for protium, one for deuterium, two for tritium), would have only one proton.

Helium has two neutrons and two protons in its nucleus.
30 neutrons in the most stable isotope of iron (Fe-56).
Hydrogen only has one proton. A Hydrogen-3 atom contains one proton and 2 nuetrons. This is because atoms of a certain element can vary in the amount of nuetrons. The're called isotopes.
An oxygen atom typically has 8 protons and 8 neutrons in its nucleus.
