the average atomic weight of all the hydrogen in the universe is just a bit greater than the mass of a protium atom.
deuterium and tritium.
Deuterium is an isotope of hydrogen that has 1 neutron (an ordinary hydrogen atom has none). A nucleus of tritium has 2 neutrons.
Hydrogen, Deuterium, Tritium
No. Not hydrogen itself. However there are a total of three isotopes of hydrogen - Hydrogen, Deuterium, and Tritium. Tritium is radioactive
The difference between deuterium and tritium is one neutron. Deuterium has one proton and one neutron, 12H, while tritium has one proton and two neutrons, 13H.
Isotopes of Hydrogen
Protium (1H), Deuterium (2H), and tritium (3H)are the three isotopes of hydrogen.
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.
hydrogen Hydron, tritium, deuterium
There are three forms of Hydrogen (these are known as isotopes). These are normal hydrogen, deuterium and tritium.
Hydrogen normally doesn't but its isotopes deuterium and tritium do. hydrogen
These are the Hydrogen isotopes with the least mass: Hydrogen 1-protium Hydrogen 2-deuterium Hydrogen 3-tritium
