Covalent and Ionic Bonds

Front

What is a covalent bond?

Back

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

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

What is the main reason elements bond?

Back

To become stable by achieving a full outer electron shell.

Front

How do ionic bonds form?

Back

Ionic bonds form when one atom transfers electrons to another atom, creating oppositely charged ions that attract each other.

How do covalent bonds form?

Back

Covalent bonds form when two atoms share one or more pairs of electrons.

Front

What are the properties of ionic compounds?

Back

Ionic compounds typically have high melting and boiling points, are soluble in water, and conduct electricity when dissolved.

Front

What are the properties of covalent compounds?

Back

Covalent compounds usually have lower melting and boiling points, may not be soluble in water, and do not conduct electricity.

Front

What is an example of a covalent bond?

Back

An example of a covalent bond is the bond between two hydrogen atoms in a hydrogen molecule (H2).

Front

What is an example of an ionic bond?

Back

An example of an ionic bond is the bond between sodium (Na) and chlorine (Cl) in sodium chloride (NaCl).

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons.
