Periodicity 0.0 / 5 ? ChemistryThe Periodic TableASAQA Created by: izzybook25Created on: 01-05-18 20:17 Where are metals in the periodic table? Block S and D 1 of 16 Where are non-metals in the periodic table? Block P 2 of 16 What are elements which fall on the line between metal and non-metal called? Metalloids 3 of 16 In which direction do metals get more reactive on the table? Going down 4 of 16 In which direction do non-metals get more reactive on the table? Going up 5 of 16 In period 3, which elements are metals? Sodium, magnesium and aluminium 6 of 16 In period 3, which element is a giant covalent semi metal? Silicon 7 of 16 In period 3, which elements are molecular non-metals? Phosphorus, sulfur and chlorine 8 of 16 In period 3, which is a noble gas? Argon 9 of 16 Which molecular structure in period 3 has the highest boiling point, why? Silicon, S8 - more van de waals due to 8 atoms creating the one molecule 10 of 16 Why do boiling points going across the metals? More delocalised electrons and higher charge 11 of 16 What is the trend in atomic radii across period 3? Radii decrease due to more protons increasing the charge creating a stronger pull on outer electrons 12 of 16 What is the trend in ionisation energies across period 3? Ionisation energies increase due to protons increasing but electrons staying in the same shell - making it harder to lose one electron 13 of 16 What occurs between group 2 and 3 in relation to ionisation energies? Drop due to group 3's electrons are in a higher energy P sub shell so less energy is require to remove one electron. Group 2 is in a S-subshell 14 of 16 What occurs between group 5 and 6 in relation to ionisation energies? Group 6 electron is easier to remove as it experiences electron repulsion therefore requires less energy 15 of 16 What part in successive ionisation energies tells us which group the element is in? The first big jump 16 of 16
