Chemical Bonding

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.

What is the Lewis Structure for oxygen?

Back

The Lewis Structure for oxygen shows two pairs of shared electrons between two oxygen atoms, represented as O::O.

Front

What type of bond is formed in CaCl2?

Back

CaCl2 is an example of an ionic bond, formed between calcium and chlorine.

Front

What type of bond is predicted between magnesium (Mg) and chlorine (Cl)?

Back

The bond between magnesium and chlorine is predicted to be ionic.

Front

Which category of elements usually forms negative ions?

Back

Nonmetals usually form negative ions.

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.

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.

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 are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds occur when electrons are shared unequally between atoms, while nonpolar covalent bonds occur when electrons are shared equally.
