The PeriodicTable

By the end of this session you will be able to....

• Use the periodic table to identify elements based on their symbols.

• Recognize how the periodic table can be used to predict the chemical properties of an element.

• Locate noble gases, alkali metals, metals and non-metals on the periodic table, and describe their chemical properties.

Alkali Metals

• The following elements all react explosively with water. These elements are shaded in green on periodic table, located in group 1.

• Lithium

• Sodium

• Potassium

• Rubidium

• Cesium

• Francium

Halogens

• The following elements are all poisonous and explode when combined with other elements. These elements are shaded in red on the periodic table, located in group 17.

• Fluorine

• Chlorine

• Bromine

• Iodine

• Astatine

Alkali Earth Metals

• The Alkali Earth metals are less reactive than the Alkali metals, but more reactive than other metals. These elements are shaded in yellow on the periodic table, located in group 2.

• Beryllium

• Magnesium

• Calcium

• Strontium

• Barium

• Radium

Noble Gases

• The following elements do not react when combined with other elements. These elements are shaded in purple on the period table.

• Helium

• Neon

• Argon

• Krypton

• Xenon

• Radon

Periodic Table Groups

• Elements with similar chemical properties are lined up into groups (columns) on the periodic table. When elements have similar chemical properties it means they react the same way. For example: all Alkali metals explode when mixed with water.

• The atomic mass and reactivity of an element increases as you get further down the periodic table.

• Because the atomic mass increases, the size of the atoms also increase as they get further down the periodic table.

Periodic Table Groups

• Elements with similar chemical properties are lined up into groups (columns) on the periodic table. When elements have similar chemical properties it means they react the same way. For example: all Alkali metals explode when mixed with water.

• The atomic mass and reactivity of an element increases as you get further down the periodic table.

• Because the atomic mass increases, the size of the atoms also increase as they get further down the periodic table.
