2 6.1: History of the periodic table 1) 2) Mendeleev s Periodic table Problems with early periodic tables
3 History: Mendeleev s periodic table For thousands of years only a few elements were known - Gold, Silver and copper As chemists began using the scientific method, the rate of discovery of elements increased Chemists used the properties of elements to sort them into groups. In 1869 Dimitri Mendeleev organized the known elements into groups based on repeating properties and increasing atomic mass Mendeleev left spaces for elements still not discovered (?) as he predicted their properties and discovery In the late 1800s Gallium & Germanium which has properties similar to Mendeleev s predictions for elements between Zn and As were discovered. Then his periodic table gained acceptance. Mendeleev s published periodic table from 1869
4 History: Problems with early periodic tables When Mendeleev created his periodic table, scientists did not know about a) the structure of the atom or b) that atoms of each element had a unique number of protons (atomic number) Number of protons is the same in all isotopes of an element. Proton numbers are different only between different elements So arranging elements based on atomic mass- the sum of protons and neutronsis not a good way to arrange elements based on their properties as it ignores the elements with chemically similar isotopes A better way to groups elements is by Atomic number which is unique to each element.

7 1) Key Points on the arrangement of Elements: 1) Arranged in order of increasing atomic number (protons) 2) 7 periods and 18 groups /columns 3) Each period represents a Principle Energy Level (n=1 to n=7) 4) More elements in higher numbered periods because there are more orbitals in those energy levels 5) Elements within a group have similar properties 6) Properties of elements in a period change as you go from left to right but the properties within a period repeat as you move from one to another period 7) Three broad classes of elements: majority of the elements are metals (left side), some are nonmetals (upper right) and in between these are a few metalloids 8) Across a period elements become less metallic Periodic law: When elements are arranged in order f increasing atomic number there is a periodic repetition of their physical and chemical properties
