-DATE Experiment 19 PERIODIC TABLE PRELIMINARY QUESTIONS t a) List two o characteristics common to all elements in Group VIIA. common List two characteristics common to all elements in Group IA, excluding hydrogen. b) 2What is meant by periodicity of properties? s cousedt 3. Contrast metals and non-metals periodic tables were based upon listing elements by increasing atomic weights. The modern bble is based upon increasing menis, find and list three pairs of elements that would be in revere order on a table based on atomic lements, find upon increasing atomic numbers. On a modern table, ignoring the lanthanide and actinide weights. 227
