How many neutrons does hydrodgen have?

Answer 1

Hydrogen has three naturally occurring isotopes:

Protium or 1H has only a single proton in its nucleus (no neutrons) and is by far the most common isotope (~99.9885% of all hydrogen atoms are protium)

Deuterium or 2H has one proton and one neutron in its nucleus and is the second most common isotope (~0.0115% of all hydrogen atoms are deuterium)

Tritium or 3H contains one proton and two neutrons in its nucleus and occurs in very small trace amounts in nature (less than 0.00001%)

4H with 3 neutrons, 5H with 4 neutrons, 6H with 5 neutrons and 7H with 6 neutrons have been produced artificially in the lab but they all have half-life of less than 10-21 seconds.

Answer 2

There are three naturally occurring isotopes of hydrogen. The vast majority are hydrogen -1 or protium, which does not have any neutrons. Hydrogen-2 (deuterium) has 1 proton and the extremely rate hydrogen 3 (tritium) has 2 neutrons.

Answer 3

Hydrogen has 0 neutrons. Mass (protons + neutrons) - Atomic number (protons) = number of neutrons.

Answer 4

0. Neutrons are the "glue" that holds the protons in the nucleus together. As hydrogen only has one proton there is no need for this "glue"

Answer 5

none
