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.
Lithium iodide
ionic lithium loses its one valence electron, becoming a positive ion iodine gains a valence electron (giving it all eight valence electrons), becoming a negative ion
Iodine accepts one electron to achieve noble gas configuration. Strontium loses two electrons to achieve noble gas configuration. Nitrogen accepts three electrons to achieve noble gas configuration. Krypton already has a noble gas configuration.
if lithium loses one electron it attains the stable noble gas electron configuration of helium. hence it is highly reactive.
