Question

1. differentiate ionic from covalent: use the word bank to complete the following chart. you can use this information to create flashcards to study with.

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

Explanation:

To differentiate ionic and covalent bonds:

• Electrons: Ionic = transferred; Covalent = shared.
• Materials: Ionic = metal + nonmetal; Covalent = nonmetal + nonmetal.
• Melting point: Ionic = high; Covalent = low.
• Product: Ionic = crystal lattice; Covalent = molecules.
• Conducts current: Ionic (aqueous/molten) = yes; Covalent = no.
• Solubility in Water: Ionic = usually soluble; Covalent = usually insoluble (polar covalent may vary).

Answer:

	Ionic Bond	Covalent Bond
Materials	Metal + Nonmetal	Nonmetal + Nonmetal
Melting Point	High	Low
Product	Crystal Lattice	Molecules
Conducts Current	Yes (aqueous/molten)	No
Solubility	Usually Soluble	Usually Insoluble
