In this video you will learn all the science for this topic to get a grade 9 or A* in your science exams!
Metals are found to the left of the stepped line in the periodic table. Metals have 1, 2 or 3 electrons in their outer shell. Metals have a giant metallic lattice structure as they consist of positive metal ions held in a fixed position with a sea of delocalised electrons that move randomly throughout the metal. These delocalised electrons have temporarily left the outer shell where they move throughout the metal. There is a strong electrostatic force of attraction between the protons in the nucleus and the negative delocalised electrons. This electrostatic force keeps the positive metal ions in a fixed position and is very strong. Metals have a neutral charge because the atoms have an equal number of protons and electrons.
