What is the molecular structure of carbon dioxide (CO2)?

Back

The molecular structure of carbon dioxide consists of one carbon atom double bonded to two oxygen atoms, forming a linear shape.

Why do atoms form bonds?

Back

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

What are valence electrons?

Back

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

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.

Front

What is an example of an ionic compound?

Back

An example of an ionic compound is sodium chloride (NaCl), formed from sodium and chlorine.

Front

What is an example of a covalent compound?

Back

An example of a covalent compound is water (H2O), formed from hydrogen and oxygen.

Front

What role do electronegativity values play in bond formation?

Back

Electronegativity values determine how strongly an atom attracts electrons; a large difference in electronegativity between two atoms typically leads to ionic bonding.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond where electrons are shared unequally between two atoms, resulting in partial charges.
