Ionic compounds do not have prefixes but covalent compounds have prefixes. “Aluminum chloride” is a ionic compound and "boron tri-chloride” is a covalent compound.
Aluminium chloride is a covalent bond. Actually, it is a ionic bond with a higher degree of covalency. This is due to polarization. Cations are very polarizing, while anions are very polarizable. The higher the charge of the cation will increase the degree of distortion of the electron cloud surrounding the anion. This shows that aluminum chloride has a considerable degree of covalent character. Hence, the electron pair will be shared among the atoms. Since, aluminum ion have a very high charge, ie 3+, hence the difference between the calculated and the experimental value of the lattice energy will be very high. Besides, the atomic radius of the chlorine atom is very small. Therefore, aluminum chloride is a covalent bond.
Yes: bonds between calcium cations and oxide anions. Each of these has an absolute value of electric charge of 2, calcium being positive and oxide negative, so that the compound is neutral with only a single one of each kind of ion it contains.
