Cesium is a metal and fluorine is a nonmetal. When a metal and nonmetal bond, they form an ionic bond.

How do you explain why CsF is ionic and OF2 is covalent?

CsF is the bond between an alkali salt and a non-metal, and in this case a halogen. The reason for the bond is because they complete the valance electron (the outer electrons) of each other. Cs, when ionized, is Cs+. F is F-. The bond between two ions is, consequently, and ionic bond. OF2, however, is covalent because it is composed of non-metals. The Oxygen atoms, nor the Fluorine atoms were ionized (changed into 2+ or - respectively) before they were combined. In order to bind, they have to form a covalent bond, where the electrons also complete each other's shells. However, the force that keeps them together is immensely stronger than an ionic bond. Long story short - metal to non-metal - ionic non-metal to non-metal - covalent the rest are detailed and not necessary for your question


Is FeSO4 a ionic or covalent bond?

It is ionic


Is CsF a ionic compound or covalent compound?

No it is impossible.A covalent bond occurs between 2 or more non-metal atoms. As the atoms can't both gain electrons, they share up to 3 of their valence electrons to achieve a full valence electron shell arrangement. The atoms bond to achieve a full outer shell of 8 electrons (except hydrogen and helium). There are no ions present because the electrons are shared and do not alter the charge. Cs is a metal and cannot covalently bond with Cl. They will form ions however and create an ionic compound


Is Br2 an ionic or covalent?

Br2 is a covalent compound. It consists of two bromine atoms sharing electrons to form a covalent bond.


Is CsF a non-polar covalent bond?

No, caesium is a group 1 metal, with low electronegtivity. With fluorine it forms an ionic compound.

No, it is ionic


Which bond is stronger and stable LiI or CsF?

The CsF bond is stronger and more stable than the LiI bond. This is because the ionic bond strength increases with increasing ionic charge and decreasing ionic radius. Cs+ has a larger ionic charge and a larger atomic radius compared to Li+, resulting in a stronger and more stable CsF bond.
