CHEMISTRY REVISION 4. 1 Atomic structure and the periodic table Name the parts of the atoms Label the mass and atomic number (LHS) & electrons, protons & neutrons (RHS): Balance the following equation: Ca + 02 Ca. O Cl 2 + Al Al. Cl 3 ABCFill in the following table: Why are atoms neutral? How can mixtures be separated? Summarise each one and describe what the may be used for How do you work out the neutron number? Define element and give 3 examples Define compound and give three examples Define mixture and give three examples KEY WORDS: proton, neutron, electron, nucleus, neutral, positive, negative, shells, relative mass, charge, atomic number, mass number, symbol, isotope, abundance, formula, relative atomic mass, react, chemical bond, properties, balanced, physical, mixture, crude oil, soluble, insoluble, solvent, filtration, evaporation, crystallisation, boiling point, fractional distillation

CHEMISTRY REVISION 4. 1 Atomic structure and the periodic table State how each of these scientists aided in the development of the model of the atom Dalton: Group 1 – the alkali metals: Describe the properties: JJ Thomson: Rutherford: Describe the chemical properties: Write an equation to show they react with water and describe the tests for the products Neils Bohr: James Chadwick: Why does reactivity increase down the group? State how each of these scientists aided in the development of the modern periodic table: Dalton: Group 7 – the halogens Newland: Describe the types of compounds formed: Group 0 elements What is displacement? Write an equation to show displacement in action, state the colour change that will be seen Mendeleev: Why does reactivity decrease down the group? Describe how the modern periodic table is arranged: Transition metals: Describe the physical properties: Modern Table How are elements are ordered in the modern periodic table? What information about elements is used to group them now? What determines what row elements are in now? What determines what column elements are in now?
