Final answer:
Ionic bonding is expected in NaF and OF2 compounds.
Step-by-step explanation:
Ionic bonding is expected in the following compounds:
In NaF, sodium (Na) is a metal and fluorine (F) is a nonmetal. The sodium atom donates one electron to the fluorine atom, forming a positive sodium ion (Na+) and a negative fluorine ion (F-). These ions are held together by electrostatic attractions, forming an ionic bond.
In OF2, oxygen (O) is a nonmetal and fluorine (F) is also a nonmetal. Since both elements are nonmetals, they are likely to form a covalent bond rather than an ionic bond.
