Structure of an atom

At the end of this activity, students should be able to:
– give short descriptions of models of the atom according to Thomson and Rutherford
– name the components of the nucleus and determine their charges
– describe spectrum analysis
– state Bohr's postulates
– calculate the radius of the n-th orbit in an atom of hydrogen, given the radius of the first orbit
– calculate the energy (in electronvolts) of an electron located in the n-th orbit and the energy emitted or absorbed when the electron moves from one orbit to another
– explain the symbolic notation of a nucleus
– give the definition of an isotope.
