Chapter 3- Elements and the Periodic Table

State key events in the historical development of the periodic table.

Mendeleev noticed that patterns apperead when the elements were arranged in a pattern of their increasing atomic mass. He left 3 blank spots for elements that had not been discovered. He predicted their proertise. Today the periodic table was arranged by the atomic number

List the information in the periodic table and descrobe how it is organized.

Each square in the period table usally includes the elements atomic number, chemical symbon, name and atomic mass. It is arranged by ATOMIC NUMBER. There are 18 families in vertical colums. 'there name has to do with the first element in the colum. In each family they normally have similar propertise. Periods are horiantal rows. There are 7 rows. The elements change from very reactive metals to inreactive gases.The elements in the periods do not have allike propertise.

Describe uses of the periodic table.

You can predict the elements propertise by the location of the element on the table.

Describe chemical and physical propertise of metals.

Physical proertise- hardness, shininess, malleability, ductibility, most are good conductors
Chemical Properites- FINISHHHHH
