(Generally, elements at the top of the table have the lowest boiling points.) A has atomic number of 8. The compound IW is less stable than FW. (Alkali metals with more energy levels form more stable compounds.) X is a noble gas. J has 2 protons. I is an alkali metal. Z has the lowest atomic mass in its group. M has 5 valence electrons.

https://info.5y1.org/lowest-atomic-number_1_a6379f.html
Quantum numbers specify the properties of atomic orbitals and the properties of electrons in orbitals. The principal quantum number indicates the main energy level (shells) occupied by the electron. As the number increases, the electron's energy and its distance from the nucleus increases. There are four shapes of orbitals (sublevels):
