As a metal, lithium will lose electrons to have a ful valence shell. How manyvalence electrons will it lose to have full valence
Free_Kalibri [48]

Answer:

It will lose 1 electron

Its charge will be 1+, or simply (+)

Explanation:

Lithium it's located in the group one of the periodic table, the Alkali, and by rule, all Alkali are always gonna loose one electron during a chemical reaction to form a positive ion.

The charge is explained by the fact that, if lithium looses one electron, then it wi have less number of electrons than protons, meaning that, if there's a higher number of protons (positive charge), then the charge will be positive. And since the atom loosed one electron then its charge will be 1+

For example, during a chemical reaction calcium is always gonna loose 2 electrons, so its charge's gonna be Ca2+
