* F2 (Diatomic Fluorine): The bond in F2 is called a covalent bond. This is because the two fluorine atoms share their electrons to achieve a stable electron configuration. They are nonpolar covalent bonds because the electrons are shared equally between the two identical fluorine atoms.
* OH- (Hydroxide ion): The hydroxide ion is called an ionic compound. This is because the oxygen atom has gained an extra electron, giving it a negative charge (-1), while the hydrogen atom has lost its electron, giving it a positive charge (+1). The opposite charges attract, forming an ionic bond.
In Summary:
* F2: Covalent bond (nonpolar)
* OH-: Ionic compound
