Hydrogen.
The number of protons defines the element. If an atom has six atoms, then it can only be carbon. If it has six neutrons, then it is 12C.
Isotopes of the same element have different number of neutrons.
Atoms of the same element with varying numbers of neutrons are isotopes.
The only element without any neutrons is Hydrogen-1, which has a lone proton.
There is no ELEMENT which contains no neutrons HOWEVER there is an isotope of hydrogen called protium which is a single proton surrounded by a single electron.
Hydrogen.
The element neon is a pure element made of only neutrons, electrons, and protons.
Hydrogen is the only element without any neutrons.
Neutrons
Hydrogen.
21 protons and 24 neutrons in the only stable for. But there can be as few as 15 and as many as 39 neutrons.
Hydrogen ion is the only element that has no neutron and one proton. That is why it is basically a proton.
The element hydrogen is the only element that lacks neutrons in its nucleus, consisting only of a single proton and an electron.
Isotopes are atoms of the same element that are only different by the number of neutrons they have
