Atoms Combining and Allotropes Quiz

A covalent bond is an electrostatic force of attraction between positive nuclei and a shared pair of electrons.

Covalent compounds generally have low melting and boiling points, while ionic compounds have high melting and boiling points.

Covalent compounds do not conduct electricity in water because they do not produce ions upon dissolution.

<p>Allotropes are different structural forms of the same element; an example is graphite, where each carbon atom is covalently bonded to three others in layers.</p> Signup and view all the answers
