The answer is no, not in the same sense as planets revolves around the sun. There is one fundamental principle in QM which prevents you from tracking the position of those electrons in any given time.shina said:An nucleus of an atom is really surrounded by circular orbits or not.
Bohr's model of atom has long been put aside and replaced by modern QM.shina said:So what is true, according to Bohr's model of atom electron moves around nucleus in a specific place which is later considered orbit.
What is meant by "orbit" around the nucleus does not exactly have the same physical meaning as the planetary orbits. Orbit in QM mechanics refers to the so-called subshell of the corresponding atom. Following the theory of each electron being subjected under an effective potential, it turns out that you can describe the orbit/subshell of each electron similar to those as in hydrogen-like atom. The maximum number of electrons allowed to occupy a given orbit/subshell is required by Pauli exclusion principle.shina said:And why there is a pattern that orbit k can contain only two electrons, orbit l can contain only 8 electrons and so on.
Yaa I am truly satisfied with you but I don't know the reason that why limited number of electrons are there in discrete shell around nucleus of an atomblue_leaf77 said:The answer is no, no in the same sense as planets revolves around the sun.

I am fully satisfied with you mfb. Thanks for your replymfb said:Pauli principle: No two electrons can be in the same state. The innermost shell just has two states (spin up and spin down for the same wave function in space), the next shell has 8 (4 pairs of spin up and down each), and so on. A very reasonable sounding, but not really accurate model: larger shells have "more space" for more different states. A better explanation would need some more understanding of quantum mechanics.
The atom nucleus is the central part of an atom that contains most of its mass. It is made up of positively charged protons and neutral neutrons.
The orbital path of an atom nucleus refers to the circular or elliptical path that electrons take around the nucleus. These paths are also known as energy levels or shells.
Electrons are arranged in the orbital path around the nucleus in a specific order according to their energy levels. The first energy level can hold a maximum of 2 electrons, the second can hold up to 8, and the third can hold up to 18.
The orbital pattern in the atom nucleus determines the chemical and physical properties of an element. The number and arrangement of electrons in the orbital path determine how an atom will interact with other atoms.
The orbital path and pattern play a crucial role in determining the stability of an atom nucleus. Atoms with a full outer energy level tend to be more stable, while those with incomplete outer energy levels tend to be more reactive.
