ionic bomding

Question 1

what are ions

Answer 1

• ions are charged particles
• they can be single atoms Cl^- or groups of atoms NO_3^-
  *

Question 2

when do ions form

Answer 2

ions form when atoms lose or gain electrons

Question 3

why do atoms lose or gain electrons

Answer 3

to try and get a full outer shell to be stable

Question 4

what happens when metals form ions

Answer 4

they lose electrons to form positive ions (cations)

Question 5

what happens when non metals form ions

Answer 5

they gain electrons to form negative ions (anions)

Question 6

what ions do group 1 ,2, 6, 7 form

Answer 6

• group 1 form +1
• group 2 form +2
• group 6 form -2
• group 7 form -1

Question 7

in groups 1 and 2 is it easier or harder to remove electrons

Answer 7

easier to rewove electrons from outer shell so the elements get more reactive

Question 8

in groups 6 and 7 is it easier or harder to remove electrons

Answer 8

harder for nucleus to attract extra electrons to form ions so the elements get less reactive as you go down

Question 9

what happens when ions with opposite charges form ionic bonds

Answer 9

• when a metal and non metal react
• the metal loses electrons
• non metal gains electron

Question 10

what type of forces form an ionic bond

Answer 10

• strong electrostatic forces
