No a neutron is not an element it is a part of an atom. Just like an electron or a proton.
or like a fetus is not a cat is is the part of a cat
The neutron is found inside the nucleus of the atom.
Be
yes, H-1 atom has no neutron
the element that can be used as a neutron source is beryllium
Neutron
Absorption of neutrons by an element depends on neutron cross-section data for that element at the energy of interest. The absorption cross-section gives the probability of a neutron being absorbed by an atom of the element. Measuring the absorptions at a certain neutron energy can help in determining the propensity of an element to absorb neutrons at that energy level.
Neutron emission from a nucleus can change the atomic mass of an element without affecting its atomic number. This can result in the formation of a different isotope of the element. Neutron emission can also make the nucleus more stable by reducing the neutron-to-proton ratio.
Hydrogen is the only element without any neutrons.
There is no element with the neutron number 30.69. Neutron number is always a whole number as it refers to the total number of neutrons in an atom's nucleus. The closest whole number to 30.69 is 31, so an element with a neutron number of 31 could be gallium (atomic number 31).

There is an isotope of hydrogen called 'protium', which only has 1 proton and 1 electron, with no neutron.
The element is hydrogen and the isotope is tritium (1H3)
