Why does every element except hydrogen need at least one neutron in its neucleus?

Every element except hydrogen needs at least one neutron in its nucleus because it needs attractive force from the strong nuclear interaction to counter the electrostatic repulsion between the protons.

Is hydrogen gas a element?
No. Although hydrogen is an atom, it doesn't exist by itself (except as an ion). Hydrogen gas is a hydrogen molecule made of two hydrogen atoms.
Which two particles make up most of the mass of a hydrogen-2 atom?
The proton and the neutron make up most of the mass of a hydrogen-2 atom.
How many electrons are in first shell of sodium?
The first electron shell of any element is the one s shell. Every element except hydrogen has 2 one s electrons.
Why does caesium explode in water?
Cesium is, except for Francium, the most reactive element of the alkaline metals. It explodes in water because it rapidly evolves Hydrogen gas and heat. The explosion results from the hydrogen gas blowing the boiling water out of the container and then igniting.
What is argon made from?
Argon, like any other element, is made of protons, electrons, and neutrons*. It can not be made from anything else, except by nuclear reactions. _______________________________ *Except that the hydrogen-1 isotope does not contain neutrons.
What is the first element after hydrogen that which has a neutron?
Helium. All elements have neutrons except hydrogen.
What is found in the nucleus of all elements except for hydrogen?
A neutron, although this is not always the case as there are hydrogen atoms with neutrons, but hydrogen atoms are the only one which are able to not have a neutron.
Is a molecule a neutron?
No. a neutron is a subatomic particle found in the nuclei of all atoms except for hydrogen-1.
What element has A neutrons in its nucleus?
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.
Is a neutron smaller than an atom?
An atom is larger than a neutron; a neutron is a part of any atom except a hydrogen atom.
Are they more than a single neutron in an atom?
yes (except for the two isotopes of hydrogen).
All of these illustrations show isotopes of the element hydrogen except?

Where would you find a neutron in a atom?
The neutrons of an atom are located in the nucleus (except hydrogen-1 isotope which has no neutrons).
Where in a atom would you find a neutron?
The neutrons of an atom are located in the nucleus (except hydrogen-1 isotope which has no neutrons).
Is hydrogen gas a element?
No. Although hydrogen is an atom, it doesn't exist by itself (except as an ion). Hydrogen gas is a hydrogen molecule made of two hydrogen atoms.
What kind of elements have electron and proton and neutron?
All of the elements have protons and electrons, and all elements except hydrogen have neutrons.
Which two particles make up most of the mass of a hydrogen-2 atom?
The proton and the neutron make up most of the mass of a hydrogen-2 atom.
