Document Content and Description Below

1.1 A Simple model of the atom, symbols, relative atomic mass, electronic charge and isotopes State that everything is made of atoms and recall what they are 12/13 Describe what elements and compo... unds are 12/14 State that elements and compounds are represented by symbols; and use chemical symbols and formulae to represent elements and compounds 14 HT ONLY: Write balanced half equations and ionic equations 15 Describe what a mixture is 16 Name and describe the physical processes used to separate mixtures and suggest suitable separation techniques 16/17/18 Describe the difference between the plum pudding model of the atom and the nuclear model of the atom 19 State the relative charge of protons, neutrons and electrons and describe the overall charge of an atom 12 Calculate the number of protons, neutrons and electrons in an atom when given its atomic number and mass number 12 Define the term relative atomic mass and why it takes into account the abundance of isotopes of the element 13 Describe how electrons fill energy levels in atoms, and represent the electron structure of elements using diagrams and numbers 20 4.1.2 The Periodic Table Recall how the elements in the periodic table are arranged 22 Describe how elements with similar properties are placed in the periodic table 22 Explain why elements in the same group have similar properties and how to use the periodic table to predict the reactivity of elements 22 Describe the early attempts to classify elements 21 Explain the creation and attributes of [Show More]
