Is CaSO4 Ionic or covalent?

You cannot tell from a formula whether an compound is ionic or molecular. The distinction is arbitrary at best, and there are actually very few purely ionic compounds. Al2S3 will be somewhere between ionic and covalent. Depending what level you are at and wherer you are taught different classifications of aluminium sulfide are given. See link for one view. Al2S3 is a colorless high melting compound, the aluminium atoms are in tetrahedral coordination in the most stable forms. This is line with the size difference between S and Al. The electronegativity difference between Al and S is ony 0.97. These are factors that need to be taken into account when making a decision. My view is partially covalent partially ionic!

What is the formula for ionic compound formed between B and O?

Boron triuoxide, B2O3. (If teacher says its ionic then that's OK) B2O3 is more covalent than ionic the electronegativity difference is only 1.4 and boron is not a metal. It is best described as a giant covalent molecule.


Is AgNO3 covalent or ionic?

Disilver oxide, Ag2O silver(I) oxide is ionic using the simple rule of thumb "metal plus non metal" gives an ionic compound. But looking more deeply it is probabaly best described as covalent. Checking the electronegativities, Ag (1.93) O (3.44) the difference is only 1.5- which is borderline for ionic and covalent. Looking at the crystal structure, Ag2O as the same structure as Cu2O. Each silver atom has 4 near neighbour oxygen atoms and each oxygen has two near neighbour silver atoms. This very different from the more typical "antifluorite structures" of the more obviously ionic alkali metals where the metal atoms have 4 oxygen near neighbours and the oxygen atoms 8 metal atom near neighbours. Additionally in Ag2O three atoms are in a line O Ag O indicating sp hybridisation.
