1 Ni metallic solid 2 C6H6 molecular solid 3 KF ionic solid 4 H2O molecular solid 5 CsI covalent solid Which is incorrect?

Answer 1

The incorrect answer is CsI.

CsI is a crystalline solid. The types of solids listed above represent the properties that the molecular structure has. For example, many molecular solids consist of carbon and hydrogen, with an occasional diatomic molecule thrown in such as O2. CsI is under the category of a salt, which also has a crystalline structure. And ionic solids are solids made out of molecules with oppositely charged ions. And if you look at the location of the two elements on the Periodic Table you can see that they have opposite charges.

Metallic solids....well they contain metal, lol.
