Electronic configuration of Lithium is 2,1. So in second shell it can hold 1 electron.If it will combine with some other element it will give out its electron in second shell.
Lithium has the electronic configuration
1s2 2s1
There are therefore 2 electrons in the first i.e. lowest energy shell.
Zero, Lithium has three electrons 1s2 2s1

the number of electrons found in the third shell of an helium atom are nill because its atomic number is 2
The third shell of an atom can hold a maximum of 18 electrons. This shell consists of three subshells - s, p, and d - with each subshell being able to accommodate a certain number of electrons. The s subshell can hold up to 2 electrons, the p subshell can hold up to 6 electrons, and the d subshell can hold up to 10 electrons, totaling 18 electrons in the third shell.
The element lithium has 3 protons and 3 electrons.
The sodium atom (Na) has 11 electrons. The electron configuration of sodium is 2-8-1. The third noble gas shell is the second energy level or shell, which can hold a maximum of 8 electrons. Therefore, the number of electrons in the third noble gas shell of sodium is 1.

Sulfur has six electrons in its third electron shell.
3. 2 in the first shell, 1 in the second
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
Just the one electron in Lithium's outer shell is responsible for its chemical properties.
18 electrons

First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
There are 12 electrons in the electron shell of magnesium, the same number as protons. As for the outermost shell, it would be 3s2, meaning there are two electrons in the third "s" shell.
