The Periodic Table organizes the chemical elements by atomic number. Dmitri Mendeleev is considered the inventor of the Periodic Table in 1869, arranging 63 known elements in order of atomic weight and properties. The table groups elements with similar properties together and orders them periodically by atomic number, metals, nonmetals, and metalloids. Elements in the same group have the same number of valence electrons.

1. The Periodic Table
By: Jesse Weinert

2. What is the Periodic
Table?
A table of the chemical elements arranged in
order of atomic number

3. Father of the Periodic
Table
• Considered the inventor of the Periodic
Table
• Invented it by organizing 63 known
elements containing the element’s symbol,
atomic weight and its characteristic
chemical and physical properties

4. Table Organization
The Periodic Table is organized by atomic
number, metals, nonmetals, metalloids,
periods, groups, and stability.

5. Relationship between
Elements
• In each family or group the elements have
the same number of valence electrons
• The elements are grouped according to
element, which are solids, liquids, and gases
• Going left or down the table the radius
gets bigger on each element

6. Hydrogen
• Atomic Number: 1
• Symbol: H
• Mass: 1.00794
• Uses: Lifting blimps off ground, potent fuel

7. Helium
• Atomic Number: 2
• Symbol: He
• Mass: 4.002602
• Uses: Inflating bal.oons, is added to oxygen
tanks so divers can breathe more easily

8. Gold
• Atomic Number: 79
• Symbol: Au
• Mass: 196.96657
• Uses: Conducts electricity, drawn into wire
