periodic-table-shells-valence-_TITLE_SLIDE.gifThere are 3 important things you have to learn from this page:

  1. What information do the PERIODS (rows) on the Periodic Table give you?

  2. What information do the GROUPS (columns) give you.

  3. How to use this information to draw diagrams showing what the atoms of the different ELEMENTS look like i.e. HOW all the particles are arranged! This is called the ELECTRONIC CONFIGURATION or STRUCTURE of the atom.Slide2.JPGSlide3.JPGperiodic-table-shells-valence Summary- 4.gif

SO.... What are 3 important things you have learnt ???

  1. The PERIODS (rows) on the Periodic Table tell you the NUMBER OF SHELLS that element has.


  2. the GROUPS (columns) tell you how many VALENCE ELECTRONS the atoms (element) has i.e. the nº of electrons in its OUTER SHELL.


  3. How to use this information to draw diagrams showing what the atoms of the different ELEMENTS look like i.e. HOW all the particles are arranged! This is called the ELECTRONIC CONFIGURATION or STRUCTURE of the atom.
