however, to think of electron orbits as rigid shells containing a number of different possible electron orbitals. As an atom's atomic number increases, its shells must accommodate an increasing number of electrons. The outermost shell is called the valence shell; the period number...

Heavier halogens have more electrons in their valence shells. This can make Van der Waals forces stronger, slightly increasing boiling point. The Halogens The halogens are members of what is called Group 17 on the periodic table, which are named because they represent the seventeenth column from...

One of the responses of an atom to the removal or supply of energy is the transition of electrons from a lower energy level to a higher energy level or the reverse. The transition depends on the amount of energy removed or supplied. ...

And the corresponding solutions are given, including the wave function and energy of the ground state of the interstitial hydrogen. Comparing this solution with a free H, we see that the atomic property of interstitial H is markedly changed. Instead of simply repeating the past work, this short...
