Name the element which has no neutrons in the nucleus of its atom.

The atom of which element has no neutron in its nucleus ?

Why was it necessary to consider the existence of neutrons in the nucleus of an atom?

An atom of an element has 29 electrons. The nucleus of the atom contains 35 neutrons. Find the number of protons in the nucleus and the mass number.

The mass number of an anion, X^(3-) , is 14. if there are ten electrons in the anion, the number of neutrons in the nucleus of atom, X_2 of the element will be
