1.

Mention the types of the following solids (1) CaF2 (2) SiC (3) CaCo3 (4) ZnS

Answer»

Answer:

1) Ionic

2) Molecular

3) Ionic

4) Ionic

Explanation:

Since $\\\tt Ca^{2+} , F^{1-}$ and $\\\tt Ca^{2+} , CO_{3}^{2-}$ and $\\\tt Zn^{2+} , S^{2-}$ have electrostatic ATTRACTION between then it's an ionic solid.
SiC has a network because of covalent bonds and 4 electrons in Silicon's and Carbon's valence shell.
