Question 1

What happens to electrons during covalent bonding

Answer 1

They are being shared

Question 2

What happens to electrons in ionic bonding

Answer 2

They are transferred from one atom to another, creating ions

Question 3

What is a cation

Answer 3

An ion that has a positive charge

Question 4

What is an anion

Answer 4

An ion that has a negative charge

Question 5

What makes a molecule polar

Answer 5

there is an unequal sharing of electrons causing there to be a (+/-) side, caused by different electronegativites

Question 6

What makes a molecule non-polar

Answer 6

there is an even distribution of electrons in a molecule

Question 7

Is a polar molecule soluble or insoluble in water

Answer 7

it is hydrophilic, it can dissolve in water

Question 8

Is a non-polar molecule soluble or insoluble in water

Answer 8

it is hydrophobic, it can’t dissolve in water

Question 9

Are ions soluble or insoluble in water

Answer 9

they are hydrophilic, it can dissolve in water
