LiI. Iodine is less electronegative. Li is very polarising and I- is more readily polarised (fajans rules)
The electronegativity difference of 3.0 indicates an ionic bond rather than a polar covalent. However LiF is not very soluble, like other Li salts. This is due to a partial covalent character in the bond due to the high polarising power of the small Li+ ion which distorts the electron cloud round the anion. The extent of this effect caused by cations is predicted in "Fajan's Rules"
CH4 (methane) is not likely to have ionic bonds. This compound is composed of covalent bonds between carbon and hydrogen atoms. The other compounds listed contain ions and are more likely to have ionic bonds.
Ionic. The bonding in LiF is primarily ionic, as lithium (Li) donates an electron to fluorine (F) to form a stable compound, with a strong electrostatic attraction between the positively charged Li+ ion and the negatively charged F- ion.
To draw a dot and cross diagram for LiF, NH3, and CO2: Lithium fluoride (LiF) will have lithium donating one electron to fluorine, forming a single ionic bond. Ammonia (NH3) will show nitrogen sharing one electron each with three hydrogens, forming three covalent bonds. Carbon dioxide (CO2) will have carbon sharing electrons with two oxygens, forming two double covalent bonds.
The chemical formula for lithium fluoride is LiF.

yes more than lif itself ;)

LiF is the chemical formula of lithium fluoride.
LiF ( Note the use and position of capitals and small case letters.
Lithium reacts with fluorine to form an ionic compound, LiF. The rest all form covalent compounds
