Thus, the further the distance between the electron and the nucleus, the harder it is to gain, but the easier it is to lose electron]]> 2018-12-05 06:56:43 UTC https://padlet.com/casey_stone3/t50wyuxj38ot/wish/311240176 Reactivity https://padlet.com/casey_stone3/t50wyuxj38ot/wish/311240231 As we move down a group, the distance from the nucleus to the outer shell increase which reduces the attraction between them. That is why the elements further down are more reactive.]]> 2018-12-05 06:56:59 UTC https://padlet.com/casey_stone3/t50wyuxj38ot/wish/311240231 As you maove down a group, the atoms reactive, because outer electrons are further. 2 atoms lose and gain electrons https://padlet.com/casey_stone3/t50wyuxj38ot/wish/311240473 2018-12-05 06:58:46 UTC https://padlet.com/casey_stone3/t50wyuxj38ot/wish/311240473 Elements further down the group are samadhi_jayasuriya https://padlet.com/casey_stone3/t50wyuxj38ot/wish/311240740 2018-12-05 06:59:35 UTC https://padlet.com/casey_stone3/t50wyuxj38ot/wish/311240740 There are trends in the reactivity of elements as you move further down the group. E.g.: Potassium is more reactive than Lithium https://padlet.com/casey_stone3/t50wyuxj38ot/wish/311240840 2018-12-05 07:00:21 UTC https://padlet.com/casey_stone3/t50wyuxj38ot/wish/311240840 Electrons samadhi_jayasuriya https://padlet.com/casey_stone3/t50wyuxj38ot/wish/311240891 It's easier to lose electrons but it's harder to gain them. 
The positive charge of the nucleus attracts electrons and holds them in place.
