Bohr's model of the atom included <u>energy levels</u> that Rutherford's model did not have.
<h2>Further Explanation;
</h2><h2>An atom </h2>
- An atom is the smallest particle of an element that takes part in a chemical reaction.
- It is made up of a nucleus and energy levels.
- Atoms contain sub atomic particles; electrons found in the energy levels, neutrons and protons found in the nucleus of the atom.
- Electrons are negatively charged, protons are positively charged while neutrons have no charge.
- The positive charge of protons gives nucleus a positive charge which attracts the opposite charged electrons.
- This attraction holds electrons in atoms and holds atoms to one another in many compounds.
<h3>Rutherford' model
</h3>
- According to Rutherford's model an atom contains a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus similar to the structure of the Solar system.
- This model of the atom failed to explain why electrons were not pulled into the atomic nucleus by the attraction of opposite charges of the nucleus and electrons.
<h3>Bohr's model </h3>
- According to Bohr's model such that an atom was made up of a nucleus which is positively charged and is encircled by electrons in fixed energy ranges called orbits or energy levels.
- Bohr model showed that the electrons in atoms are in orbits of different energy around the nucleus.
- Therefore; Bohr model was able to conclude that the electrons were limited to existing in certain energy levels, like standing on the rungs of a ladder.
