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)
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.
A compound word with chalk is chalkboard.
An ionic compound is an example of a chemical compound.
A covalent compound, not ionic
