2. 1. The Periodic Table of Elements
The periodic table is an arrangement of the chemical elements.
Ordered by their atomic number (number of protons), electron configurations, and recurring chemical properties.

3. Mendeleev’s Periodic Table

4. 2. Period
A period is the name given to a horizontal row of the periodic table.
The periodic table has seven periods.
Period 1 contains only two elements: hydrogen and helium.

5. 3. Group or Family
A group (also known as a family) is a column of elements in the periodic table of the chemical elements. 

6. 4. Metals Majority of the elements are metals.
A substance (as gold, tin, copper, or bronze) that has a more or less shiny appearance, is a good conductor of electricity and heat.

7. 5. Metalloid
An element with properties between the typical metals and nonmetals.
They usually have some properties of metal.
(boron, silicon, or arsenic)

8. 6. Alkali Metals
The alkali metals are a group of elements in the periodic table.
They are all in the first column of the periodic table. Hydrogen is in
the 1st column but is not in this group.
They are shiny, soft, metals. They are very reactive.

9. Alkali Metals

10. 7. Alkaline Metals/Alkali Earth Metal
This family consists of beryllium, magnesium, calcium, strontium, barium, and radium.
These chemical elements occupy the second column of the periodic table.

11. 8. Transition Metals The elements in group 3-12 of the periodic table.
This is the most familiar metals like iron, copper, nickle, silver, and gold.
Most are hard and shiny.
They are good conductors of electricity.

12. 9. Non-Metal
A chemical element that lacks the characteristics of a metal.
Ex: hydrogen, carbon, nitrogen, phosphorus, oxygen, sulfur, and selenium.

13. 10. Inert/Noble Gas
In the right-hand column of the periodic table of elements is a
group know as the noble gases.
Ex: helium, neon, argon, krypton,
xenon, and radon. .
