Ions are electrically charged particles formed when atoms lose or gain electrons 1 of 8 What do metal atoms form? positive ions- they lose an electron 2 of 8 What do non metal ions form? negative ions- they gain an electron 3 of 8 What are ionic bonds? The strong electostatic attraction between oppostitely charged ions 4 of 8 How can you work out the charge on a metal ion? the number of ions formed by a metal is equal to the group number of the metal 5 of 8 How can you work out the charge on a non metal ion? The number of charges on an ion formed by a non metal ion is equal to the group number minus eight 6 of 8 What is ionic bonding? ionic bonding is when metals react with non metals, electrons are transferred from the atoms to the non metal atoms, forming ions. 7 of 8 What are the elements in group 1 called? Alkali metals 8 of 8
