As a neutral atom, sodium possesses 1 electron in its outermost (3rd) energy level. As a 1+ ion, it possesses 8 electrons in its second energy level, forming an octet, which is the optimum number of electrons for sodium to possess in its outermost energy shell.
An oxygen atom has eight electrons. The first electron shell can contain two electrons so that shell is filled leaving six electrons left. Since the second electron shell can contain up to eight electrons, the remaining six electrons go into the second shell. Since the second shell is the outermost shell, there are six electron's in the outer energy level.
Valence electrons describe the number of available electrons for bonding. The group number describes outermost electron. The elements in same group has same valence electrons.The number of electrons available for bonding are the valence electrons. In an element, the group number is equal to the number of valence electrons. So the number of electrons available for bonding can be identified by the group number.
Aluminum has an atomic number of 13. Thus, neutral aluminum has 13 protons and 13 electrons. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p1. We can see that 3 is the outermost shell and that there are 3 electrons found there.

It depends on the number of electrons in the outer valence shell in the atom
Noble gases are very stable because their outermost electron shells contain the maximum number of electrons that those outermost shells can possess. This is a correct statement. Yes.
A neutral aluminum atom has 13 electrons. However, an aluminum ion has a greater or fewer number of electrons, and is therefore positively or negatively charged.
