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.

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.

1

Noble gases do not react with other elements.

2

Noble gases explode upon contact with other elements.

3

Noble gases produce hydrogen gas upon contact with other elements.

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.

35

Groups

  • Noble Gases (Group 18) - Do not react with any elements

  • Alkali Metals (Group 1) - React explosively with water.

  • Halogens (Group 17) - are poisonous.

  • Alkaline Earth Metals (Group 2) - are less reactive than other metals Non
