Further Chemistry - The Modern Periodic Table

HideShow resource information

BREAKTHROUGH was when the structure of the atom was discovered

When first released, many thought of the periodic table as unimportant as there was little evidence

When newly discovered elements fit into gaps Mendeleev had left, this provided convincing evidence.

Many more scientists saw that table was useful for predicting elements' properties - it really worked

LATE 19TH CENTURY - Structure of atom discovered and matched up well with periodic table

Periodic table is now accepted by scientists as very important and useful summary of atomic structure

MODERN PERIODIC TABLE is based on electronic structure - arranged in order of atomic (proton) number

  • Can be used to find the detailed arrangement of electrons in an atom of any element - with this you can…
