KS3 Science Independent Learning In this Independent Learning tasks the skill you will be developing is: To be able to find information from diagrams Website To help: LearningScienceNumeracy Atoms Over the years Many Scientists have put forward ‘models’ that they have arrived at from their research of what they understand an atom to look like……. Firstly came : ‘J.J Thompson’s ‘Plum Pudding ‘ model which showed that ‘atoms were tiny balls of positive charge with tiny negative particles stuck inside ( a little like plums in a plum pudding!!) – the negative particles he called ‘ELECTRONS’ . A Little while later Ernest Rutherford and Niels Bohr developed a model from the findings of their research which is the widely recognised model that we use today….. With each atom being made up of a number of sub – atomic particles : Protons and Positive (+ ve) Elctrons are Negative (- ve) and Neutrons are Neutral Each element in the Periodic Table has its own Atomic Number ; Number of Proton (which is the same as the number of Electrons Mass Number ; Number of Protons and number of Neutrons And are shown on the ‘Periodic Table’ like the symbol of Na (Sodium) To be able by to find information from diagrams All of these numbers can be calculated simply locating the element in the ‘Periodic Table’ locating the Atomic Number and locating the Mass Number Science Independent Learning KS3 Look at the following atoms. Lithium Now Complete the Table using the ’Atom’ diagrams above and your knowledge from the lessons ……… Atom Atomic number (from Periodic Table) Atomic mass (from Periodic Table) Number or protons Number of neutrons Number of electrons e.g.Hydrogen 1 1 1 0 1 Helium Lithium Beryllium Boron Carbon Nitrogen Mark ………… Improvements:……..……..……..…….……..……..……..……..……..……..……..…….……..……..……..……..……..……..……..…….……..……..……..……..…….. ……..……..…….……..… ..……..……..……..……..…….……..……..……..……..……..……..……..…….……..……..……..……..……..……..……..…….……..… ….……..…..……..……..…….……..……..……..……..……..……..……..…….……..……..……..……..……..……..……..…….……..… To be able to find information from diagrams
