The Periodic Table was developed in 1869 and it revolutionised science. It's organised into groups and periods, and an element's position can tell us a great deal . To revise what you learned in Year 10 and year 11, have a go at this GCSE chemistry quiz
For some transactinides, the belonging on a group in the Periodic Table has been agreed only on computational basis. This is the case of Mt, placed in the 9-group even if was not possible to experimentally study its chemistry and to verify similarities with the behavior of the lighter homol...
Periodic table – Group 1 The alkali metals have a silvery, shiny surface when they are first cut. However, this goes dull very quickly as the metals reacts with the oxygen in the air. e.g. sodium + oxygen sodium oxide 4Na(s) + O2(g) 2Na2O(s) Lithium, sodium and pota...
