KAP Bonding review 2025

Two properties of ionic compounds are:

• Low melting point and form crystals

• Poor conductors as solids and transfer electrons

• form positive and negative ions, and have low melting points

• Poor conductors as solids and share electrons

The type of bond that results from the attraction that bonds two nonmetals together by sharing electrons.

• Covalent bond

• Ionic bond

• Metallic bond

• Hydrogen bond

The compound H₂O would have which properties?

• Low melting point and be a poor conductor of electricity

• form crystals and have a high melting point

• be a good conductor but have a low melting point

• be malleable and ductile and be solid at room temperature.

In forming chemical bonds, atoms tend to attain:

• a state of higher energy

• the electron configuration of noble gas atoms

• the electron configuration of halogen atoms

• all of the above
