The only element without any neutrons is Hydrogen-1, which has a lone proton.

hydrogen 1
hydrogenEdit.Whoever wrote the answer above clearly is an idiot. At the moment there is no element with 0 neutrons. However, there are theories to an element known as element X. This element is obviously complete theory.By the way hydrogen has 1 neuron not 0.
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.
neutrons
isotopes have varying amounts of electrons ^ The above is wrong. Isotopes of an element vary in the amounts of neutrons within the nucleus only.
The isotope of zirconim, 91Zr, has 51 neutrons. In order to solve this problem, one must know that an element's atomic weight is the average of its number of protons and neutrons (only neutrons are variable). Since the atomic number is the number of protons, the atomic number subtracted from the atomic weight gives the number of neutrons. An element in period 5 that has this many neutrons is found to be zirconium (the isotope 91Zr).
Hydrogen is the only element without any neutrons.
To provide the attractive binding of the nuclear strong force, without adding to the electromagnetic force. Without neutrons, the only chemical element would be hydrogen.
Atoms of the same element with varying numbers of neutrons are isotopes.
Only hydrogen has un-isotopic atoms without a neutron. Hydrogen can sometimes though have one or so neutrons in its isotopes. The other elements must have neutrons to keep the protons from repelling each other in the atom's nucleus.

Every element has a specific number of protons, which is how an element is identified. That gives its atomic number. The number of neutrons can vary, and therefore is not useful in identifying an element.
The only element that has one proton and no neutrons is a hydrogen atom.
The element neon is a pure element made of only neutrons, electrons, and protons.
You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.
