The periodic table overview: Know the different regions of the periodic table Be able to identify types of atoms based on their position in the periodic table. Know what groups and periods are and be able to use them to identify and describe elements. Groups and periods: Be able to identify elements based on group and period number. Be able to describe elements in terms of their group and period numbers. Know that elements within a group have similar properties. The history of the periodic table: Be able to list similarities and differences between Mendeleev’s table and Newlands. Be able to describe why Mendeleev’s table was accepted and its framework remained in use. The structure of the atom: Be draw a general labelled diagram of an atom. Know the three subatomic particles and where each is found within an atom. Be able to assign the correct charge and mass for each subatomic particle. Mass number and atomic number: Be able to define atomic and relative mass number. Be able to identify atoms based on atomic and relative mass number. Know that atoms are ordered by atomic number in the modern periodic table. Be able to calculate the number of neutrons in an atom. Trends down groups. Group 1 metal and water demonstration: Be able to describe the observations when group1 metals are added to water. Be able to write word and balanced symbol equations for group 1 metals with water. Be able to describe the chemical and physical trends going down group 1. Group 7: Know that the reactivity of group 7 elements decreases going down the group. Know that the M.P and B.P and masses of group 7 elements increases going down the group. Be able to describe properties of group 7. Be able to describe the reaction of chlorine with hydrogen. Group 0: Know that the group 0 are the noble gases and they are unreactive. Know that the M.P and B.P and masses of group 0 elements increases going down the group. Know that Group 0 elements are monoatomic and be able to relate this to them having full outer shells of electrons. Class comments
