Atomic structure,computer artwork. In the centre of the atom is the nucleus (dollar sign),made up of a tightly-packed cluster of protons and neutrons. Four electrons are orbiting around the nucleus. This classical atomic model is known as the Bohr Model,after the Danish physicist Neils Bohr. However,in modern quantum physics it has proved impossible to precisely locate the position of atomic electrons. Instead they are represented by fuzzy clouds,large areas within which there is a high probability of an electron being found | |
