Properties and applications of Materials Assignment 2 Task 1 (P1) I. Describe the structure 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

the number of protons and the number of neutrons make up the atomic mass of an element‚ but not the electrons? We generally do not use the number of electrons when calculating the atomic mass of an atom because they weigh so little (precisely 1/1836 AMU)‚ and only in precise calculations are the masses of the electrons included in atomic mass. 2. What was the difference between Mendeleev’s table and Mosley’s new arrangement? Mendeleev arranged the 63 elements know at his time in order of increasing
