chemical bonding (8.5-8.8)

Question 1

step 1 of drawing lewis structure

Answer 1

start with structural molecular formula (know which atoms are attached to each other)

Question 2

step 2 of drawing lewis structure

Answer 2

sum pu valence electrons from all atoms, taking into account overall charge

Question 3

step 3 of drawing lewis structure

Answer 3

complete octet around atoms bonded to the central atom with lone pairs, subtract those electrons

Question 4

step 4 of drawing lewis structure

Answer 4

place any remaining electrons on the central atom

Question 5

step 5 of lewis structure

Answer 5

if there are not enough give the central atom an octet, move paired of electrons to add a second or third bond

Question 6

step 6 of lewis structures

Answer 6

use differend bonding structures that follow the octet rule
