Unit 2 - Chemical Bonding & Nomenclature (UNIT TEST)

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 valence electrons.

Front

What is a double covalent bond?

Back

A double covalent bond is a type of covalent bond where two pairs of electrons are shared between two atoms.

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 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.

Front

What is the molecular geometry of a molecule with the formula AX3?

Back

The molecular geometry of a molecule with the formula AX3 is trigonal planar.

Front

How many electrons are shared in a single covalent bond?

Back

Two electrons are shared in a single covalent bond.

Front

What determines the melting point of ionic compounds?

Back

The melting point of ionic compounds is determined by the strength of the electrostatic forces between the ions.

Front

What is the significance of valence electrons in bonding?

Back

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

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.

Front

What is a polar covalent bond?

Back

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