Ionic and Covalent Bonds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, resulting in the formation of charged ions that attract each other.

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 type of atoms typically form covalent bonds?

Back

Covalent bonds typically form between two nonmetal atoms.

Front

What is the main characteristic of ionic bonds?

Back

Ionic bonds are characterized by the transfer of electrons from one atom to another, leading to the formation of positive and negative ions.

Front

In ionic bonding, what do metals tend to do?

Back

In ionic bonding, metals tend to lose valence electrons.

Front

In ionic bonding, what do nonmetals tend to do?

Back

In ionic bonding, nonmetals tend to gain valence electrons.

Front

What is an example of a molecule that contains a covalent bond?

Back

An example of a molecule that contains a covalent bond is water (H2O).

Front

What is the difference between ionic and covalent bonds?

Back

The main difference is that ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is a common property of ionic compounds?

Back

A common property of ionic compounds is that they tend to form crystalline structures and have high melting and boiling points.

Front

What is a common property of covalent compounds?

Back

Covalent compounds often have lower melting and boiling points compared to ionic compounds.
