The elements that accept the electron of Lithium are Fluorine, Chlorine, Bromine, and Iodine.
Metals and nonmetals are the elements in the periodic table that gains and lose electrons to form chemical bonds.
The metals are a compound that loses electrons and nonmetals gains electrons to form a chemical bond.
Lithium has been a group 1 element with 1 valence electron. It has been bonding with the nonmetals that accept the electrons and form the bond. The elements complete their octet and become stable.
The nonmetals that require an electron to complete their octet are halogens. Thus, the elements that accept the electron of Lithium are Fluorine, Chlorine, Bromine, and Iodine.

Answer: -
0.2 moles of NaCl are contained in 100.0 mL of a 2.0 M solution
Explanation: -
Strength of NaCl = 2.0 M
Volume of NaCl solution = 100.0 mL
=
= 0.1 L
Number of moles of NaCl = volume of NaCl x Strength of NaCl
= 0.1 L x 2.0 M
= 0.2 moles
0.2 moles of NaCl are contained in 100.0 mL of a 2.0 M solution
