including the atomic structure of the element copper. Copper has a symbol Cu. It is a metal with a very high thermal and electrical conductivity. Pure copper is soft and malleable when it is freshly exposed the surface has a reddish-orange colour. It has an atomic mass of 63.546 g.mol -1 and an atomic number of 29. The electrons per energy level for copper go 2‚8‚18‚1. Copper has an atomic number of 29‚ thus meaning it contains 29 protons and 29 electrons. Copper has 35 neutrons. It has many uses such

centigram balance and the electronic balance. Using the centigram balance‚ the mass‚ in grams‚ of a copper slug will be determined by both direct weighing and weighing by difference techniques. Using an electronic balance‚ the wight of a copper slug will be determined by also utilizing direct weighing and weighing by difference. Average mass of a copper slug will be calculated using five (5) copper slugs and an electronic balance. Lastly‚ the mass of two unknown weights will be determined using the

Aim To Find the Number of Moles of Water of Crystallisation in Copper (II) Sulphate salt. Introduction Water of crystallisation is the term given to the molecules of water that are used to build up a crystal lattice in some ionic compounds.In copper II sulphate the blue crystals would be impossible without using water molecules to act as ’scaffolding’ within the structure CuSO4.5H2O. When this is heated the water molecules are driven off and the blue crystals become a white powder. As most
