Chapter 2 - Chemical Bonding

Question 1

isolable

Answer 1

capable of being obtained in a pure state

Question 2

net-neutral compound

Answer 2

empirical formula has total charge of zero

Question 3

metallic bond

Answer 3

electrons shared between many atoms simultaneously and are free to flow between the atoms

Question 4

electronegativity

Answer 4

tendency of atom in molecule to attract electrons to itself

Question 5

electron deficient

Answer 5

group 13 elements sometimes only have max 6 electrons after bonding

Question 6

hypervalent

Answer 6

3rd and later elements of p-block can have more than 8 valence electrons

Question 7

free radical

Answer 7

compound that contains unpaired electrons on a atom

Question 8

best resonance structure

Answer 8

minimal formal charges, negative formal charge on the most electronegative element

Question 9

chemically reasonable resonance structure

Answer 9

• magnitudes of formal charges are small
• lighter elements are not hypervalent
• represent typical bonding of elements

Question 10

isomer

Answer 10

same molecular formula but different arrangement of atoms
