Answer:
Lithium loses one electron to fluorine and forms ionic bond, having formula .
Explanation:
Lithium is the element of the group 1 and period 2 which means that the valence electronic configuration is .
Fluorine is the element of the group 17 and period 2 which means that the valence electronic configuration is .
<u>Thus, lithium loses 1 electron and become positively charged. Fluorine on the other hand accepts this electron and become negatively charged.</u> This is done in order that the octet of the atoms are complete. <u>These both ions then form ionic bond as their will be electrostatic interaction between the two oppositely charged ions.</u>
Thus, the formula of calcium chloride is .
