Why atoms combine and the love song of Sodium Chloride

Lyrics for the song here

We had a series of lessons explaining why atoms combine. (bohr diagram worksheets, make sure you get them from me!)

We learned the skill of how to write Bohr diagrams for atoms and for ions.  And we did section 4.1 of the study guide for homework.  Note the answer key at the end of the guide.

We will have a class quiz based on our in-class work on Monday, Jan 26.  Tomorrow's lesson will focus on Lewis structures and lots of practice with Bohr diagrams

The Periodic Table: The Lego set of the Universe

The universe is made of MATTER and ENERGY.
Matter is anything with mass and volume.  Everything is made of matter. All matter is made of subunits we call ATOMS, which themselves are made of subatomic particles such as:
NEUTRONS, PROTONS and ELECTRONS.

Today we sorted lego and built things and categorized what we built.  This activity is meant to illustrate the big lego set of the universe, the PERIODIC TABLE is organized in these ways:
 SIZE,
FAMILY
PERIOD
METALS AND NON METALS

A family - A COLUMN of elements which share similar characteristics. Each of these elements tend to react the same way. Examples of families:
Alkali Metal Family
Halogen Gas Family
Noble Gas Family

Period - A ROW of elements on the periodic table is called a period.  Each of these elements have the same number of electron shells.

Metals and Nonmetals:  This periodic table puts metals on one side and nonmetals on the other.
