M3 Review: Chemical Bonding (Chem)

Front

What is a chemical bond?

Back

A chemical bond is a lasting attraction between atoms, ions, or molecules that enables the formation of chemical compounds.

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.

What is the formula for a compound formed from K⁺ and N^-3?

Back

K₃N

Front

What is the formula for a compound formed from Na⁺ and S^-2?

Back

Na₂S

Front

What is the molecular structure of water (H₂O)?

Back

Water has a bent molecular structure due to the two lone pairs of electrons on the oxygen atom.

Front

What is the molecular shape of SCl₂?

Back

The molecular shape of SCl₂ is bent.

Front

What is the correct structure for carbon dioxide (CO₂)?

Back

Carbon dioxide has a linear structure with a double bond between carbon and each oxygen.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to form compounds in ways that give them eight valence electrons, achieving a stable electron configuration.

Front

What is a polyatomic ion?

Back

A polyatomic ion is a charged species composed of two or more atoms covalently bonded, which can act as a single unit in chemical reactions.

Front

What is the significance of valence electrons in bonding?

Back

Valence electrons are the outermost electrons of an atom and are involved in forming bonds with other atoms.
