A covalent bond is formed by atoms sharing electrons; whereas, an ionic bond can be defined as the electrostatic attraction that binds oppositely charged ions together.
covalent
SF2 forms a covalent bond. Sulfur and fluorine have similar electronegativities, so they share electrons to form covalent bonds rather than transferring electrons to form ionic bonds.
NO is covalent.
NO is covalent.
It is ionic
The bond is covalent.
The covalent bond is weaker.
The F-F bond (in F2) is covalent, and non polar covalent at that.
No, it is ionic
No, but the bond in sodium chloride is covalent.
The bond is covalent. If the bond is made by transferring electrons then it is an ionic bond, but if they are sharing the it is covalent.
Magnesium chloride has an ionic bond.
