Answer : The chemical compound lithium fluoride contains an ionic chemical bond because electrons are transferred.
Explanation :
Covalent compound : It is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound.
The covalent compound are usually formed when two non-metals react.
Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.
Ionic compound are usually formed when a metal reacts with a non-metal.
In lithium fluoride, lithium is an alkali metal and has one valence electron and fluoride is a non-metal and has 7 valence electrons.
When lithium atom donates an electron to a fluoride atom then it forms an ionic compound that is lithium fluoride (LiF).
Hence, the chemical compound lithium fluoride contains an ionic chemical bond because electrons are transferred.
