Chemical Bonding

Front

What is a covalent bond?

Back

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

Front

What type of elements typically form covalent bonds?

Back

Covalent bonds typically form between nonmetals.

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 nonmetal.

Front

Which type of elements usually form negative ions?

Back

Nonmetals usually form negative ions.

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 correct Lewis structure for BF3?

Back

The Lewis structure for BF3 shows boron (B) in the center with three fluorine (F) atoms bonded to it, with no lone pairs on boron.

Front

What type of bond occurs between a metal and a nonmetal?

Back

Ionic bonding occurs between a metal and a nonmetal.

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 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.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.
