Developing the table
Explain Mendeleev's mass ordering, chemical groupings, gaps and property predictions.
Explain how later discoveries supported Mendeleev and why modern tables use atomic number.
Reading the table
Identify periods, groups and the general positions of metals and non-metals.
Link main-group chemical similarities and group numbers to outer-shell electrons.
Explain full outer shells and the group 0 exception, including helium.
Electronic arrangements
Write and draw electronic configurations of neutral atoms among the first 20 elements.
Explain the limits of the first-20 shell model and distinguish diagrams from real electron paths.
Predictions from arrangements
Determine an element, period and group from an electronic configuration.
Explain the increase in occupied shells down a group and related chemical behaviour.
Predict common metal and non-metal ion charges from outer-shell electrons.
