ViviThe Bohr model depicts electrons orbiting the nucleus in fixed circular paths, while the modern model describes electrons as existing in electron clouds or orbitals around the nucleus with varying probabilities of location. The modern model is based on quantum mechanics and allows for a more accurate description of electron behavior and atomic structure.

Who was the danish scientist that proposed electrons orbit around the nucleus?
Niels Bohr, a Danish physicist, proposed the concept of electrons orbiting around the nucleus in his atomic model known as the Bohr model. This model was a significant advancement in understanding the structure of atoms and laid the foundation for modern quantum mechanics.
When was the modern atom model invented?
The modern atom model, also known as the planetary model, was proposed by Danish physicist Niels Bohr in 1913. This model refined the understanding of how electrons orbit the nucleus in distinct energy levels.
What is the difference between a Rutherford model a Bohr model and a Cloud model?
The Rutherford model proposed that atoms have a dense nucleus surrounded by orbiting electrons. The Bohr model improved upon this by suggesting that electrons orbit the nucleus in specific energy levels or shells. The cloud model combines aspects of both, recognizing that electrons do not move in fixed orbits but exist in regions of probability called electron clouds around the nucleus.
Who invented the atomic model?
The atomic model was developed by various scientists over time, with contributions from Niels Bohr, Ernest Rutherford, and John Dalton. However, the modern atomic model that we use today, with electrons existing in energy levels around a nucleus, was largely proposed by Niels Bohr in 1913.
How many electrons can the first shell hold in any Bohr model?
The first shell in a Bohr model can hold a maximum of 2 electrons.
