Chemistry:Overview of the elements

Groups:

• Group 1: Alkali metals (a.k.a. sodium family) with 1 electron in each atom's outer shell. Very active similar metals.
• Group 2: Alkaline earth metals (a.k.a. calcium family). These elements have 2 electrons in each atom's outer shell.
• Group 3: Nonmetallic through metallic elements with stable inner shells. 3 electrons in each atom's outer shell.
• Group 4: Nonmetallic through metallic elements with stable inner shells. 4 electrons in each atom's outer shell.
• Group 5: Nitrogen Family. Nonmetallic through partially metallic elements with stable inner shell. 5 electrons in atom's outer shell.
• Group 6: Oxygen Family. Nonmetallic through metallic with stable inner shells. There are 6 electrons in each atom's outer shell.
• Group 7: Halogen Family. Active nonmetals with stable inner shells. 7 electrons in each atom's outer shell.
• Group 8: Inert (a.k.a. noble) gases that do not combine with any other element. 8 electrons in each atom's outer shell (except for helium (2).
