The lower the atomic number the more the chance of it being likely. It depends. Are you talking about a stable element or an ion? An ion is gonna have more electrons, and will transcend further orbitals.
The transition metals undergo filling of their d sublevels. These are the elements in Groups 3-12.

There are more than two such atoms. Perhaps there was a list of atoms you had to chose from. Anyway, two such atoms are beryllium and magnesium.
A completley filled out electron level makes the atom stable
Those in group VI such as O, S, Se, Te, Po Lv.
Helium is already full. Helium atoms only need 2 electrons to be full, and Helium, as an element, already has 2.
If all the electron orbitals are filled then the atom is inert. It will not chemically react with anything. If an atom has empty spaces in the outer orbit, it will react with other elements. Electrons from other elements can share positions in the outer orbits.
the one that is completely filled
Helium.
Because the tube is partly filled with coloured spirit or alcohol so the air bubble is more visible.
In krypton atoms, the 3s and 3p sublevels are filled, i.e. 3s23p6.

undiscovered...yet, but there are a few...go forward 50 years and see

The lowest level of organization that includes atoms and molecules is the chemical level. This is the level that maintains life.
