SNC2P Periodic Table
The Periodic Table • The Periodic Table is the central tool of the chemist, but it is used by scientists in all fields of study. • It was developed by Russian Scientist, Dmitri Mendeleev, in the 1800s. • The more modern version of the table is credited to Henry Mosely.
The Periodic Table • The periodic table is essentially a list of known elements. It gives information about each element and for that reason it is a very valuable tool.
Arrangement of the Periodic Table • The horizontal rows (periods) represent a series of elements with increasing weight and changing properties.
Arrangement of the Periodic Table • The vertical columns represent a series of elements with similar chemical and physical properties. • The column are called families and each family has a specific name.
Metals and Nonmetals • Elements on the Periodic Table can be divided into metals and nonmetals. Metals are found on the left side of the zigzag line. Nonmetals are found on the right side of the zigzag line.
Metalloids • Elements that touch either side of the zigzag line have some metal properties and some nonmetal properties. These are called metalloids.
