ionic
AlF3 is a covalent compound. Although aluminum is a metal and fluorine is a nonmetal, in this case, they share electrons to form covalent bonds due to the electronegativity difference.
AlF3 has both ionic and covalent characteristics. The bond between Al and F is primarily ionic due to the electronegativity difference between the two elements. However, there is also some covalent character as the fluorine atoms can accept some electron density from aluminum.
BO is a molecular compound because it is composed of nonmetals (boron and oxygen) and forms covalent bonds.
Cr is a transition metal element, specifically chromium. It is not considered ionic or molecular on its own.
H2O is a molecular compound.
As a non-metal Phosphorous can form ionic compouds with metals and covalent compounds with other non-metals.
This is an ionic compound, for example a salt as potassium chloride.
