What is an ionic bond?

Back

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

Front

What happens to electrons in an ionic bond?

Back

In an ionic bond, electrons are transferred from one atom to another.

Front

What is the geometry of a molecule with 2 bonded pairs and 0 lone pairs?

Back

Linear.

Front

How does barium combine with sulfur to form BaS?

Back

Barium combines with sulfur by transferring two electrons and releasing energy.

Front

What defines a covalent bond?

Back

A covalent bond is formed when two atoms share one or more pairs of electrons.

Front

What are molecular substances characterized by?

Back

Molecular substances are characterized by low melting points and shared valence electrons.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is a valence electron?

Back

A valence electron is an electron in the outermost shell of an atom that can participate in forming chemical bonds.

Front

What is the significance of electron transfer in ionic bonding?

Back

Electron transfer in ionic bonding leads to the formation of ions, which are held together by electrostatic forces.

Front

What is the role of energy in the formation of ionic bonds?

Back

Energy is released when ionic bonds form, as the attraction between oppositely charged ions stabilizes the system.
