The Periodic Table

The Periodic Table Used to organize the elements What it do foo foo- “She Twerkin” by Ca$h Out Used to organize the elements Contains squares for each element

The Periodic Table Each square contains…

The Periodic Table Chemical/Element Symbols Each element has a different symbol Written with 1-3 letters First letter ALWAYS capitalized

Hydrogen H Silicon Si Carbon C Copper Cu Nitrogen N Aluminum Al Oxygen ELEMENT SYMBOL Hydrogen H Silicon Si Carbon C Copper Cu Nitrogen N Aluminum Al Oxygen O Silver Ag Chlorine Cl Gold Au Magnesium Mg Iron Fe Zinc Zn Helium He Calcium Ca Potassium K Phosphorus P Sodium Na Iodine I Fluorine F

The Periodic Table Atomic Number Atomic number = number of protons A whole number Remains the same for a given element Arranged numerically by increasing atomic number

The Periodic Table Atomic Mass Sum of the number of PROTONS and NEUTRONS in the nucleus of an atom Average Usually not a whole number

The Periodic Table Periods Horizontal row on the periodic table 7

The Periodic Table Families (Groups) Vertical columns on the periodic table 18 Similar properties

Metalloids Zigzag line on the right side of the PT that separates metals from nonmetals Found along the zigzag line Identified as metalloids have properties of both metals & nonmetals

Metals Located on the left side of the zigzag line Majority Ex. Sodium (Na), Calcium (Ca), Iron (Fe), and Aluminum (Al)

Nonmetals Found on the right side of the zigzag line Exception: Hydrogen (H) Ex. Chlorine (Cl), Oxygen (O), Sulfur (S), and Iodine (I)
