how does the position of an element in the periodic table
relate to the arrangement of electrons in its atoms?
how can you predict reactivity of elements from
their positions in the periodic table?
what is a group?
how are elements organised in the periodic table?
- how did scientists classify elements before the discovery of protons, neutrons and electrons?
- in early periodic tables, why were some elements placed in inappropriate group?
- how did Mendeleev overcame some of the problems of the early periodic tables?
- how were the gaps filled in Mendeleev's table?
- how did isotopes help?
