Question 1

Bond Dipole Moment

Answer 1

Separation of charge in a bond that depends of the difference in electronegativity and the bond distance represented by partial charges or a vector

Question 2

Covalent Bond

Answer 2

Bond formed when electrons are shared between atoms

Question 3

Dipole Moment

Answer 3

Property of a molecule that describes the separation of charge determined by the sum of the individual bond moments based on the molecular structure

Question 4

Double Bond

Answer 4

Covalent bond in which two pairs of electrons are shared between two atoms

Question 5

Electronegativity

Answer 5

Tendency of an atom to attract electrons in a bond to itself

Lattice Energy (ΔH Lattice)

Answer 7

Energy required to separate one mole of an ionic solid into its component gaseous ions

Question 8

Lewis Symbol

Answer 8

Symbol for an element or monatomic ion that uses a dot to represent each valence electron in the element or ion

Question 9

Polar Covalent Bond

Answer 9

Covalent bond between two atoms of different electronegativities; a covalent bond with a positive end and a negative end
