No, lithium has 2 electron shells (1s2 2s1) and oxygen has 2 electron shells (1s2 2s2 2p4).
A lithium atom has one electron on the outer shell. This is because there is 2 electrons maximum on the inner shell, so there is one left over for the outer shell. Hope you understand now xx
It starts with the following: K shell - 2 electrons L shell - 8 electrons M shell - 18 electrons N shell - 32 electrons it works out from there K being the first etc.
Lithium typically exists in the +1 ionic state. This means it loses one electron to achieve a stable electron configuration of 2 electrons in its outer shell.
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).
there are two protons in the first level and one proton in the second level of Lithium
The number of electron shells in a normal Lithium atom is 2. It has an electron configuration of 1s22s1
The element with 2 electrons in the L shell is Lithium with atomic number 3. The electron configuration for Lithium is 1s^2 2s^1, meaning it has 2 electrons in the L shell.
There are 1 electron in the third shell of lithium. Lithium has an atomic number of 3, so it has 3 electrons in total. The first shell can hold up to 2 electrons, and the second shell can hold up to 8 electrons, leaving 1 electron in the third shell.

A neutral atom of lithium has an electron configuration of 2,1. This means it has 1 electron in its outer shell.

Oxygen needs 2 electrons to fill it's valence shell which is why it forms a 2- ion.
Oxygen needs 2 electrons to fill its outer shell, which is the second electron shell. This shell can hold a maximum of 8 electrons. Oxygen has 6 electrons in its neutral state, so it will gain 2 electrons to achieve a stable electron configuration similar to a noble gas.
Oxidation number of Li is +1. Oxidation number of oxygen is -2.
