Individual hydrogen atoms are stable in so far as they do not decay, they are however very reactive chemically and they can easily become stabilized by bonding two hydrogen atoms each other to form a hydrogen molecule. Meanwhile, hydrogen reacts with many other elements including metals, metalloids and non metals.
A stable atom of hydrogen (H)
The atom with an atomic number of 1 is Hydrogen. Hydrogen only has one electron and is very unstable because it is very close to the nucleus and has an incomplete valence shell holla back
A completley filled out electron level makes the atom stable
Hydrogen is a diatomic element needing another one of its kind to be stable so another hydrogen atom would bond with it making H2, but there could be other elements that need just one electron to be happy can also bond with Hydrogen (like Fluorine, which makes Hydofluoric Acid).
Hydrogen atom is neutral.

Two.
In simple terms, an atom with an unstable nucleus will decompose because the protons and neutrons breaking away from one another. In a hydrogen nucleus, which consists only of a single hydrogen atom, there is nothing for it to break away from.
A hydrogen atom is only a proton and an electron. Beyond that the neutron seems to keep the nucleus together and stable. Maybe a better question is, "What is the difference between a hydrogen atom without an electron and a proton?"
hydrogen, helium, lithium, and beryllium
There are two atoms with two neutrons. One is hydrogen-3 which is radioactive. The other is helium-4 which is a stable and inert atom.
There is a concept in chemistry called valence, which is the number of bonds an atom can form to make a stable compound or molecule. Oxygen has a valence of 2, meaning it needs 2 bonds to form stable molecules. Hydrogen has a valence of 1. So, to satisfy the valences of both elements, two hydrogen atoms bond to one oxygen atom.
They have enough energy produced to fuse four hydrogen atoms into a helium atom.

Stability isn't determined by the first energy level. The only atom with less than two is hydrogen. It is a very stable atom...reactive in that it will attach to anything, but it will always be hydrogen. The atoms that readily decay (the radioactive ones) all have full first orbitals.
Yes, Chlorine atom is stable
The smallest atom is hydrogen.
