Explain Rutherford Model of Atom.
Answers
Rutherford model of atom;
1. All the positive charge and nearly all the mass of atom is present inside the nucleus, which is situated at the center of the atom.
2. Electrons revolve around the nucleus in well-defined orbits.
3. The size of the nucleus is very small in comparison to the size of an atom.
Limitations:
According to classical electromagnetic theory, the electron must radiate energy in the form of electromagnetic waves.In Rutherford atom model, an electron is revolving around the nucleus and is constantly experiencing a centripetal force. Therefore, the electron has an accelerated motion. As the revolving electron loses energy, it must spiral inwards and eventually fall into the nucleus as shown in the following diagram
So in this way the Rutherford model does not explain the stability of atom.
Hello!!
Rutherford model, also called nuclear atom or planetary model of the atom.
His model showed that an atom is mostly empty space, with electrons orbiting a fixed, positively charged nucleus.
Limitation
It could not explain about the stability of an atom
Features:
(i) The atom contains a central part called nucleus which is surrounded by electrons
(ii) The nucleus of an atom is positively charged
