Chemical Bonds Practice

Ionic compounds are usually solid at room temperature and form a crystal structure.

Anions are formed when an atom gains electrons.

Calcium (Ca) and Bromine (Br) will combine to form an ionic bond.

CO₂ represents a substance that contains covalent bonds.

8 electrons are needed in the outer energy levels for chemical stability.

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Cations are positively charged ions formed when an atom loses electrons.

Ionic compounds are formed from the transfer of electrons between atoms, while covalent compounds are formed from the sharing of electrons.
