12/2/15 and 12/3/15
Topic: Periodic Table
Objectives:

• Describe that as you move from left to right in a period (row) on the Periodic Table, the number of protons increases by one.
• Describe that elements found in the same group/family (column) have the same properties.
• Recognize that elements are grouped in the Period Table of Elements according to their properties.

                                                   Periodic Table Notes

         Students will copy and then summarize the Periodic Table Notes.

• Atomic Number is defined as the number of protons in the nucleus of an atom.Every atom of the same element has the same number of protons.
• The number of protons determines the identity of the element.
• Typically atoms have the same number of protons, neutrons and electrons.
• The mass number is the total number of protons and neutrons in an atom.
• The periodic table is arranged in horizontal rows of increasing atomic number from left to right.  It is also organized into vertical columns with similar characteristics.
• Atoms are composed of protons, neutrons and electrons.  These particles can be distinguished based on mass, location and charge.
• Protons:  1 amu (atomic mass unit), in nucleus, positively charged
• Neutrons: approximately 1 amu, in nucleus, neutral charge
• Electrons: negligible mass, outside nucleus, negatively charged.
• Period Number = Number of Energy Levels
• Valence electrons increase moving left to right across the period.
• Groups = Families. Groups have similar properties!
• Acidity increases from Group 1 to Group 18
• Solubility of Metal salts decreases from Group 1 to Group 16
• Metal Salts in water conduct electricity
• Non-metal molecules do not conduct electricity in water
• Solubility is unrelated to element type

Group 1 elements react explosively with water
