SpletExample 1.1: Calculate the number of copper atoms present in a cylinder that has a diameter and a height both equal to 1 µm. The mass density of copper is 8.93 x 103 kg/m3 and its atomic mass is 63.55 g/mol. Solution: a) The volume of the copper cylinder is given by: 3.14 x (0.5 x 10-6)2 x 1 x 10-6 m3 = 0.78 x 10-18 m3; SpletHere, the electron configuration of copper ion (Cu +) is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 10. On the other hand, the copper atom donates an electron in the 4s orbital and an electron in the 3d orbital to convert copper ion (Cu 2+ ). Atomic number, atomic weight and charge of copper ion. Cu – 2e – → Cu 2+.

Copper – Atomic Number – Atomic Mass – Density of Copper

SpletThese loose electrons are called free electrons. They can move freely throughout the metallic structure. What is the density of free electrons in copper? At room temperature, copper has free electron density of 8.4×1028m−3. The electron drift velocity in a copper conductor of cross-sectional area of 10−6m2.
