Chemical Bonding - Covalent Non-Metals: Covalent Bond and Single Covalent Bond

Question 1

covalent bonding

Answer 1

• the “sharing” of a pair of e- s by two atoms

- neither atom is willing to give up electrons or strong enough to take them away

Question 2

drawing lewis structures

Answer 2

• similar to lewis dot for atoms
• indicate non-bonded e-
• F - 1s^2 2s^2 2p^5

Question 3

single bond - sigma bond

Answer 3

• sigma bond - the bond that forms directly between two atoms
• s-s orbital overlap
• s-p orbital (end overlap)
• p-p orbital (end to end)

Question 4

sharing of electrons

Answer 4

• shared electrons - needed electrons - available electrons

- S = N - A

Question 5

group VIIA or 17 - single bonds

Answer 5

• consider halogens outer valence electrons are all 7

- need on more electron

Question 6

group VIA or 16

Answer 6

• consider outer valence electrons are all 6

- need two more electrons

Question 7

how many bonds does argon (group VII) form

Answer 7

• 0

Question 8

how many bonds does hydrogen (group i) form

Answer 8

• 1

Question 9

how many bonds does nitrogen (group V) form

Answer 9

• 3

Question 10

how many bonds does fluorine (group VII) form

Answer 10

• 1

Question 11

how many bonds does carbon (group IV) form

Answer 11

• 4

Question 12

a single covalent bond contains _____ electron(s) that is/are shared between the two atoms

Answer 12

• 2
