Series: Structure of the Atom
Radioisotopes are unstable atoms that emit radiation, and decay to form stable atoms. Some of their uses are as nuclear fuel and as tracers in medicinal fields.
According to JJ Thomson’s model for the structure of an atom, an atom consists of a positively-charged sphere and the electrons are embedded in it. The negative and the positive charges present are equal in magnitude so that the atom is electrically neutral as a whole. Show Less
Isobars are atoms of different elements with the same mass number but different atomic numbers. Isobars have different electronic configuration and possess different chemical properties.
Ernest Rutherford conducted an experiment which is known as the “Rutherford alpha scattering experiment”, in which he allowed alpha particles from a radioactive source to fall on a thin gold foil. Based on his observations of this experiment, he gave a nuclear model of an atom. Show Less
