What are metals GCSE?
Metals consist of giant structures of atoms arranged in a regular pattern. The electrons from the outer shells of the metal atoms are delocalised , and are free to move through the whole structure. This sharing of delocalised electrons results in strong metallic bonding .
Why is gold found in the earth as the pure metal GCSE?
(i) Gold is found as a pure metal in the Earth because gold is reactive.
Is a 43 a pass in combined Science?
measures? The DfE have confirmed that a grade 4 is a standard pass and grade 5 is a strong pass. For Combined Science this means that it would equate to a grade 4-4 being a standard pass.
Can you get a 9 in combined Science?
Combined Science is a double award GCSE which counts as two GCSEs. The grading scale is doubled, (there are double the marks) so students can achieve one of 17 grades: 9-9, 9-8, 8-8 through to 2-2, 2-1, and 1-1.
Why is diamond hard GCSE?
The rigid network of carbon atoms, held together by strong covalent bonds, makes diamond very hard. This makes it useful for cutting tools, such as diamond-tipped glass cutters and oil rig drills. Like silica, diamond has a very high melting point and it does not conduct electricity.
How are steel classified?
Steel can be classified by a variety of different systems such as the composition, manufacturing method, finishing method, product form, deoxidation practice, microstructure, strength level, heat treatment and quality descriptors.
What is steel GCSE?
Steels are alloys of iron that contain specific amounts of carbon (a non-metal) and certain metal elements. Different steels have different properties , depending on their composition.
What do you do if you fail your GCSEs?

What type of metal is steel?
iron alloy
Steel is an iron alloy, meaning it’s primarily composed of iron and combined with one or more alloying metals to produce new materials with unique properties.
