Periodic Table Learning Outcomes: I know the names of Group 1, 7 and 8
I know where the transition metals are found in the periodic table I know that elements I the same group share chemical properties I know where metals and non-metals are located in the periodic table Success Criteria: I can identify the group that an element belongs to. I can carry out an experiment safely to determine the conductive properties of metals and non-metals. I have engaged in a demonstration showing that elements in a group share chemical properties.

Periodic Table Arranged in order of increasing atomic number
Rows called periods, columns called groups Groups have similar chemical properties
4
Group 1- Alkali Metals React rapidly with water, produce an alkaline solution and Hydrogen gas. Metals become more reactive going down the group (Li – Fr)
5
Group 7 - Halogens Elements F and Cl are gases, Br is liquid and I is solid They exist as diatomic molecules (2 atoms in each molecule) Become less reactive going down group (F – At)
6
Group 0/8 – Noble gases Very unreactive (stable) and exist as individual atoms (monatomic).
7
Transition Metals (between groups 2 and 3)
Form brightly coloured compounds
8
The Periodic Table
9
Another way of classifying the elements is to arrange them into metals & non-metals.
The bold zigzag line shown in the periodic tables divides the metals, on the left, from the non-metals, on the right.
10
Non-metals Metals
11
Experiment 1: Metals and Non-metals
The best way to distinguish metals from non-metals is to find out if they are electrical conductors or insulators. This can be done using the circuit shown in the diagram.
12
Instructions: Test the elements in the kit to find out if they are conductors or insulators.
13
Element Metal or Non-metal Conductor or Insulator
16
Research Task Choose an element from Group 1,7 or a transition metal
17
Answer the following Questions
Name of element? When was it discovered? Where was it discovered? Who discovered it? What uses does it have? What effect has this element had on society (or the environment)?
18
You can now use this information to create an element cube.
Write your information on one side of the cube net at the back of the booklet. Cut out and build net.
