Question

ionic bond covalent bond
electrons
type of materials (metals/nonmetals)
melting point (high/low)
product (crystal lattice, molecules)
conducts a current?
other

Explanation:

Ionic bonds involve transfer of electrons from metal to non - metal, forming a crystal lattice with high melting points and conducting current in molten or aqueous state. Covalent bonds involve sharing of electrons between non - metals, forming molecules, having generally low melting points and not conducting current (except some special cases like graphite).

Answer:

	Ionic Bond	Covalent Bond
Type of materials (metals/nonmetals)	Metal and non - metal	Non - metals
Melting point (high/low)	High	Low (generally)
Product (crystal lattice, molecules)	Crystal lattice	Molecules
Conducts a current?	Yes (in molten or aqueous state)	No (generally)
Other	Strong electrostatic forces	Varying bond strengths
