The Periodic Table 0.0 / 5 ? ChemistryThe Periodic TableGCSENone Created by: Erin GoslingCreated on: 10-05-13 22:11 Group The vertical columns in the periodic table. Group no. = no. outer shell electrons 1 of 8 Period The rows going across the periodic table. Trends change gradually, but in the same way from one period to the next 2 of 8 Metals Found left and centre of periodic table. Good conductors of electricity. React to give basic oxides (pH > 7) 3 of 8 Non-metals Found to the right of periodic table. Poor conductors of electricity. React to give acidic oxides (pH> 7) 4 of 8 Group 1 (the alkali metals) Li, Na, K etc. Very reactive in air and water 5 of 8 Group 7 (the halogens) F, Cl, Br, I. Non-metals which exist as diatomic molecules (F2, Cl2 etc). 6 of 8 Displacement Used to determine reactivity of halogens. A more reactive halogen will displace a less reactive halogen from a solution of it's salt 7 of 8 Group 0 (the noble gases) He, Ne, Ar etc. Unreactive (inert) gases. Exist as single atoms (full outer shell so no need to bond). 8 of 8
