A charged atom that has a fuller outer shell 1 of 14 What is a cation? A positively charged atom 2 of 14 What is an anion? A negatively charged atom 3 of 14 How many electrons does a group 1 atom have on its outer shell 1 4 of 14 How many electrons does a group 2 atom have on its outer shell 2 5 of 14 How many electrons does a group 6 atom have on its outer shell 6 6 of 14 How many electrons does a group 7 atom have on its outer shell 7 7 of 14 To become an ion what does an atom from group 1 or 2 do? Looses 1 electron on outer shell if group 1 and 2 electrons if group 2 8 of 14 To become an ion what does an atom from group 6 or 7 do? Gains 1 electron for group 7 or two for group 6 9 of 14 What is an ionic bond? The transfer of electrons between a metal and a non metal 10 of 14 Describe the structure of an ionic bond Oppositely charged ions held together by strong electrostatic forces in a regular lattice arrangement 11 of 14 What makes an ionic bond have high melting/boiling points Strong electrostatic forces of attraction are very hard to break 12 of 14 Why does a solid ionic structure not conduct electricity The ions are not free to move so cannot transfer the current 13 of 14 Why does an aqueous or molten ionic substance conduct electricity The ions are free to move so can carry the charge 14 of 14
