2 Introduction to the Periodic Table Atomic Number ● Symbol ● Atomic Weight Element ● Compound ● Mixture

3 I am Dmitri Mendeleev! I made the PERIODIC TABLE !

4 What is the PERIODIC TABLE? o Shows all known elements in the universe. o Organizes the elements by chemical properties.

5 How do you read the PERIODIC TABLE?

6 What is the ATOMIC NUMBER? o The number of protons found in the nucleus of an atom Or o The number of electrons surrounding the nucleus of an atom.

7 What is the SYMBOL? o An abbreviation of the element name.

8 What is the ATOMIC MASS? Some call this atomic weight. o The number of protons and neutrons in the nucleus of an atom.

9 How do I find the number of protons, electrons, and neutrons in an element using the periodic table? o # of PROTONS = ATOMIC NUMBER o # of ELECTRONS = ATOMIC NUMBER o # of NEUTRONS = ATOMIC _ ATOMIC MASS NUMBER MASS NUMBER
