lithium and fluorine
Lithium donates an electron to fluorine and make the fluorine with a negative charge and a full outer shell. Lithium consequently get a positive charge and a full outer shell. They then are attracted to each other an form a giant ionic lattice.
Carbon and hydrogen are organic so they don't
Nitrogen and Oxygen are also organic.
Chlorine can form ions but not with silicon
