Look at the diagram shown below. Name the scientist who created this early attempt at a periodic table.

Describe how the modern periodic table is organized.

What breakthrough did Mendeleev make in devising a periodic table that was accepted by the scientific community?He devised the ‘law of octaves’He published the first full list of all the elementsHe left gaps in the table for unknown elementsHe arranged the elements in order of atomic weight2Which of the following statements about the modern periodic table is not true?Elements in the same group have the same number of electrons in the outer shellElements are arranged in atomic number orderThe number of shells decreases down a groupElements in the same period have the same number of shells3Where are the non-metal elements found in the periodic table?At the bottomAt the topOn the rightOn the left4Which of the following elements, shown by its electronic structure, is found in group 2 of the periodic table?2, 72, 8, 12, 8, 22, 8, 45Why do fluorine, chlorine and iodine all have similar chemical properties?They are all metalsThey all have 7 electrons in their outer shellThey are all in the same periodThey all have odd numbers of electrons
