5. Mendeleev
Russian scientist who published the first periodic table in 1869.

6. Mendeleev
He recognized that some elements have similar chemical and physical properties.
Fluorine and chlorine are both gases that burn your lungs.
Silver and copper are both shiny metals that tarnish when exposed to air.

7. Arrangement of Elements
The periodic table contains information about the structures and characteristics of the elements.

8. Arrangement of Elements
Elements are arranged in the periodic table in order of their atomic number.

9. Arrangement of Elements
“Periodic” means regular, repeating pattern, and properties of elements repeat in each period (row).

10. Periods
A horizontal row of elements in the periodic table is called a period.
The atomic numbers increase by one from left to right across a period.

11. Groups
A vertical column of elements in the periodic table is called a group.

12. Groups Groups are numbered 1–18 across the top of the periodic table.
Elements in the same group have similar properties.

13. The Lanthanide and Actinide Series
The two rows of elements at the bottom of the table are the Lanthanide Series and the Actinide Series (also called “rare earth metals”).

14. Metals
Elements that are on the left side and in the middle of the periodic table are metals.

15. Metals
Metallic refers to the properties of common metals.

16. Metals
Luster, or shine, is one property of metals.

17. Metals
Metals are also ductile and malleable.
ductile
malleable

18. Metals
Conductivity is the ability of a material to transfer electricity or thermal energy, and metals are good conductors.

19. Metals
Most metals are solids at room temperature because of their high melting point, with the exception of Mercury (Hg), a liquid at room temperature.

20. Nonmetals
Elements on the right side of the periodic table are nonmetals.

21. Nonmetals
Nonmetals exhibit properties that are the opposite of metals.

22. Nonmetals
They are poor conductors of heat and electricity, are brittle, and do not have luster.

23. Nonmetals
Nonmetals make up most of the matter in the living world.

24. Nonmetals Most are gases at room temperature. iodine carbon bromine
The solids, carbon (C) and iodine (I) are dull and brittle.
Bromine (Br) is the only nonmetal that is liquid at room temperature.
iodine
carbon
bromine

25. Nonmetals
Group 17 elements are the halogens, which are the most reactive nonmetals, and most are dangerous to humans. F

26. Nonmetals
Group 18 elements are the noble gases, which are extremely stable by themselves and occur in nature as single atoms, NOT compounds.

27. Semimetals
8 elements are semimetals, or metalloids.

28. Semimetals
Semimetals have the properties of both metals and nonmetals.
Semimetals conduct electricity but not as well as metals, so they are called semiconductors.

29. Other Periodic Tables
A variety of periodic tables are designed to provide the information needed by different groups of people.

30. Other Periodic Tables The Student’s periodic table shows the: name
state of matter

The Physicist’s periodic table also shows the:

34. Other Periodic Tables
A variety of periodic tables are designed to provide the information needed by different groups of people.

35. Other Periodic Tables
A variety of periodic tables are designed to provide the information needed by different groups of people.
