2 Periodic Table, Formulae &Equations

3 Periodic Table Here lies the body of poor old Joe He will not live no more Cos what he thought was H 2 0 Was H 2 SO 4

4 Periodic Table Learning Outcomes By the end of this session you should: be familiar with the PT and its uses be able to write chemical formulae be able to write & balance chemical equations

5 Periodic Table Metals / Non-metals + Transition Metals/ Semi-metals Groups 1-8/0 Columns of similar elements,graded props Alkali Metals, Akaline Earth Metals, Halogens & Inert gases Rows Go across. Each row a new electron shell filling Valencies 1,2,3,4,3,2,1,0

6 Formulae & Equations H 2 SO 4 H 2 CO 3 HNO 3 HCl NaOH NH 4 OH Word equation Symbols Valencies Balance Calculation

7 Elements, Compounds & Mixtures Periodic Table Atomic Number (Z) No of protons = No of box in PT Mass No (A) No of protons + No of neutrons Relative atomic mass Av mass of an atom compared to C-12
