Answer 2

An atom of deuterium has one neutron. Deuterium is an isotope of hydrogen with one proton and one neutron in its nucleus.

Answer 3

There is 1 neutron in an atom of deuterium.

Answer 4

Deuterium is an isotope of hydrogen, it has twice the mass of a hydrogen atom. A hydrogen atom's mass number is 1 so a deuterium atom would have a mass number of 2

Answer 5

Deuterium nuclei contain one proton and one neutron each and therefore have a mass number of 1 + 1 or 2.
