Periodic Table Topic - Revision
Atoms & Alchemy
-To know that everything is made of atoms
-To know that atoms of one type cannot be turned into atoms of another type
know elements are arranged in the periodic table according to atomic number (number of protons).
know elements with similar properties are arranged together in groups e.g. alkali metals, halogens.
Elements & Compounds
-Know that elements can either be a metal or a non-metal
-Understand that when a metal ‘burns’ in air metal atoms combine with oxygen atoms in the air.
-Be able to understand that elements can react together to make compounds.
-A compound is made up of two or more different atoms joined together.
-know that energy is required to split up compounds
-know that the compound is split into the elements which make it up
Metal & non-metal properties
-know the key properties of metals – strong, conduct heat, conduct electricity, and malleable
-can relate these properties to potential uses around them.
Discovery of the elements
-Some metals are found in there natural state e.g gold
-Some metals require energy to be extracted from ores e.g. copper, iron, aluminium
The alkali metals
-know that alkali metals react violently with water and air
-can describe the similarities and differences between the elements
-To know that the Halogens are Fluorine, Chlorine, Bromine and Iodine
-To recognise them as a group in the periodic table
-To know the similarities and trends in the group – colour, toxicity, boiling point
-a salt is made up from a metal and a non-metal part.
-know the flame colours for metals
Cells & Batteries
-To know that batteries produce electricity by a chemical reaction in a chemical cell.
-To understand that connecting two different metals can make a voltage.
-To understand that the two metals used in a cell need to be separated and in a salt solution.
Chemical cells joined together form a battery.
