1.f - Ionic Bonding

Question 1

what do group 1, 2, 3 elements ( metals) do to form positive ions

Answer 1

loose electrons

Question 2

what do group 5, 6,7 elements ( non- metals) do to form negative ions

Answer 2

gain electrons

Question 3

what kind of ions do group 1, 2, 3 elements (metals ) form

Answer 3

positive ions

Question 4

what kind of ions do group 5,6, 7 elements (non- metals ) form

Answer 4

negative ions

Question 5

what kind of elements do group 1 elements form

Answer 5

1+ ions ( loose 1 electron)

Question 6

what kind of elements do group 2 elements form

Answer 6

2+ ions (loose 2 electrons)

Question 7

what kind of elements do group 3 elements form

Answer 7

3+ ions ( loose 3 electrons)

Question 8

what kind of elements do group 5 elements form

Answer 8

3- ions ( gain 3 electrons)

Question 9

what kind of elements do group 6 elements form

Answer 9

2- ions ( gain 2 electrons)

Question 10

what kind of elements do group 7 elements form

Answer 10

1- ions ( gain 1 electron)

Question 11

definition of ionic bonding

Answer 11

strong electrostatic attraction between oppositely charged ions

eg. metal reacting with a non metal

Question 12

how are ions formed

Answer 12

through loss or gain of electrons

Question 13

why do ionic compounds ( giant ionic lattices) have high melting and boiling points

Answer 13

the electrostatic attraction ( forces ) between oppositely charge ions ids very strong

Question 14

can ionic compounds conduct electricity

Answer 14

only when molten or in an ( aqueous) solution

not when solid

Question 15

why do ionic compounds only conduct electricity when molten or in solution

Answer 15

the charged ions are free to move

Question 16

learn common ions sheet

Answer 16

???

Question 17

be able to draw dot- cross diagrams

only outer electrons need to be shown

Answer 17

???
