Ionic and Metallic Bonds

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions, typically between a metal and a non-metal.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move around, allowing metals to conduct electricity.

Front

Why are metals good conductors of electricity?

Back

Metals are good conductors because they have mobile electrons that can move freely throughout the metal lattice.

Front

What are cations?

Back

Cations are positively charged ions that are formed when an atom loses one or more electrons.

Front

What are anions?

Back

Anions are negatively charged ions that are formed when an atom gains one or more electrons.

Front

What happens to electrons in ionic bonding?

Back

In ionic bonding, electrons are transferred from one atom (usually a metal) to another atom (usually a non-metal), resulting in the formation of cations and anions.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have a full outer shell of eight electrons, achieving a stable electronic configuration.

Front

How do metallic bonds differ from ionic bonds?

Back

Metallic bonds involve a sea of delocalized electrons shared among metal atoms, while ionic bonds involve the transfer of electrons between a metal and a non-metal, resulting in charged ions.

Front

What is the role of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms, determining the atom's chemical properties.

Front

What is electronegativity?

Back

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