The Periodic Table

• Metals and Non-Metals
• Groups and Periods
• The Elements of Group 1
• The Elements of Group 7
• The Elements of Group 0

Metals and Non-Metals

• Explain how elements are classified as metals and non-metals.
• Use patterns to classify an element as a metal or a non-metal.
• In the Periodic Table, there are two main categories - Metals and Non-metals. There is a stepped line on the Periodic Table to show whether elements are metals or non-metals. The stepped line looks a bit like like steps. Elements on the left of the stepped line are metals. Most elements are metals. Elements on the right of the stepped line are non-metals.
• Metals and non-metals have different properties. You can tell whether an element is a metal or non-metal by its properties.
• Not all elements fit the pattern. Some elements called metalloids (which are elements next to the stepped line) have properties of a metal and of a non-metal.

Groups and Periods

• Use patterns to predict properties of elements.
• Compare patterns in the groups and periods of the periodic table.
• In the Periodic Table, the vertical columns are called groups. The horizontal rows are called periods.
• There are patterns in the properties between the groups and periods.
