The Periodic Table

  • The first “modern” organization of the periodic table was done by Dmitri Mendeleev

  • The atomic number is the numbers of protons in the nucleus

  • The symbol for the element

  • There is an element name

  • The atomic mass is a weighted average of the isotopes

    • isotopes have the same number of protons, different number of nuetrons

  • There are metals, metalloids and non-metals in the periodic table

  • Elements in a group have the same chemical proporties

    • They will behave similar to each other
