Ionic and Covalent Bonds Flashcard

Front

What are valence electrons?

Back

Valence electrons are the electrons located in the outermost energy level of an atom, which are involved in forming bonds.

Front

Why do atoms form bonds?

Back

Atoms form bonds to fill their outermost energy level, achieving stability.

Front

When are atoms most stable?

Back

Atoms are most stable when their outer shell is complete, meaning they have a full set of valence electrons.

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.

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 the Lewis Structure?

Back

The Lewis Structure is a diagram that represents the bonding between atoms and the lone pairs of electrons in a molecule.

Front

What is the chemical formula for an ionic bond between Aluminum and Oxygen?

Back

The chemical formula for the ionic bond between Aluminum (Al) and Oxygen (O) is Al2O3.

Front

What is the chemical formula for the bond between Magnesium and Chlorine?

Back

The chemical formula for the bond between Magnesium (Mg) and Chlorine (Cl) is MgCl2.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form bonds in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the formation of charged ions, while covalent bonds involve the sharing of electrons between atoms.
