Describe Rutherford's atomic model |
|
Answer» An atom is composed of positively charged particles. Majority of the mass of an atom was concentrated in a very small region. This region of the atom was called as thenucleusof an atom Atoms nucleus is surrounded by negatively charged particles calledelectrons. The electrons revolve around the nucleus in a fixed circular path at very high speed. These fixed circular paths were termed as“orbits.” An atom has no net charge or they areelectrically neutralbecause electrons are negatively charged and the densely concentrated nucleus is positively charged. A strong electrostatic force of attractions holds together the nucleus and electrons. The size of the nucleus of an atom is very small in comparison to the total size of an atom. |
