2nd answer :

outer electron configuration is the same as valence electron , you can easily find it in the period table : using the number of the group :

Group 1 : one, Group 2 :two , Group 3-12 cannot be found instead d electron count is used , group 13 : three , Group 14 : four ans so on until Group 18 : Eight

So oxygen is in group 16 so it has 6 outer electron configuration or look to the Nobel gas notation : [He] 2s2 2p4 so count the power of last orbitals 2s 2p so : 6

oxygen is in group 6, and has 8 as that valence thingy. so its 2 in the first rign and 6 in the outer ring.

since the electron configuration is 1s^2 2s^2 2p^4, then it would be 2p^4

How many valence electrons does oxygen gain?

Oxygen tends to gain two electrons to complete its "octet", making it O2- with the electron configuration 1s22s22p6


How many electrons does oxygen have to gain in order to achieve a noble-gas electron configuration?

Lithium has one valence electron. It is much easier for an atom to lose one electron than gain seven more. Lithium looses this one electron to achieve a full outer shell (the next inside shell is full).
