[He] 2s one
Lithium (Li) has the electron configuration 1s2 2s1.
.. [Li]+ [:I:]- (put the last 2 pairs above and below the "I" this wont let me) ..
The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.

The electron configuration is the number of electrons in each energy level of an element. The electron configuration of Li is, 1s2 2s1. The electron configuration of F is, 1s2 2s2 2p5.
if lithium loses one electron it attains the stable noble gas electron configuration of helium. hence it is highly reactive.
Lithium(Li) gains 1 electron to become stable.
[He] 2s1
Francium and lithium have different atomic numbers, electron configuration, Pauling electronegativity etc.
A neutral atom of lithium has an electron configuration of 2,1. This means it has 1 electron in its outer shell.
