The Bohr model!

Niels Bohr introduced the notion of electronic orbits.
It added on Niels Bohrs model and his research. And anika's cool :D
Neil Bohrs atomic model is simply called Bohrs model. It states that electrons have a certain amount of energy, so they must follow certain orbits. This is different from the modern atomic model.
The Bohr atomic model is similar to solar system.
For a while, but eventually a new atomic model came out that we still use today.
Scientists determined that electrons do not orbit the nucleus like planets. Instead, electrons can be anywhere in a cloud like region around the nucleus
Bohr's model of the hydrogen atom works well for atoms with only one electron like hydrogen, but it fails for helium because helium has more than one electron. The model does not account for the repulsion between the two electrons in the helium atom, leading to inaccurate predictions of its behavior.
The Bohr model for hydrogen is a proton orbited by an electron.
