Lewis structures

Question 1

How to draw lewis structures

Answer 1

write the atoms
Draw valence e
check for charge
make single bonds
check octet rule
Add multiple bonds if needed

central atom is the least electronegative but NEVER H

Question 2

How many e can H hold max

Answer 2

2 e

Question 3

How many e can B hold max

Answer 3

6 e

Question 4

The atoms below period 2 can

Answer 4

have more than 8 e

Question 5

FC formula

Answer 5

FC= valence e - # bonds - # Lone e

Question 6

where does charge go

Answer 6

central atom

Question 7

noble gases and electronegativity

Answer 7

noble gases are the least electronegative

Question 8

REMINDER

Answer 8

PUT CHARGE WHEN DRAWING ANIONS AND CATIONS

Question 9

Most polar happens

Answer 9

when we have the most difference in electronegativity or farther \way from each other in the periodic table and of them is electronegative

Question 10

bond order formula

Answer 10

bonds/#atoms

Question 11

bond properties covalent trends

Answer 11

more internuclear distance, higher energy, more unstable
less internuclear distance, lower energy, less unstable

Question 12

the more bonds

Answer 12

the tighter the internuclear distance is, the shorter the length, the stronger the bond and requires more energy to break so bond dissociation energy goes up

Question 13

Bond dissociation energy

Answer 13

how much energy needed to break a bond
