Chalk is primarily composed of calcium carbonate, which is a covalent compound. The bonds between the carbon, oxygen, and calcium atoms in calcium carbonate are primarily covalent in nature, involving the sharing of electrons between atoms.
Wax crayons are a mixture of different waxes and coloring agents, the waxes are paraffin waxes which are covalent compounds, alkanes, CnH2n+2. Chalk crayons traditionally consist of fine particulate naturally occuring chalk, from deposits of coccoliths, the white compound is calcium carbonate, which is ionic, the material is soft because of the particulate size. More recently blackboard chalk is made from gypsum calcium sulfate, also ionic.
The bond in chalk (CaCO3) is considered ionic. This is because it is formed between a metal (calcium) and a nonmetal (carbon and oxygen), resulting in the transfer of electrons from calcium to form ions with opposite charges.
Chalk may be a compound in the sense that all the teeny shelled animals that make it up are themselves made from compounds. (Remember, a compound is composed of usually two or more Elements, like oxygen, carbon, hydrogen, iron, sodium, and so on)
It is ionic
Bases can be both ionic and covalent in nature.

The two main types of chemical bonds are ionic and covalent.
Is CsL ionic or covalent
No, but the bond in sodium chloride is covalent.
