How does the electron-cloud model describe electrons?
Answers
Answer:
The electron cloud is not really a thing. An electron cloud model is different from the older Bohr atomic model by Niels Bohr. Bohr talked about electrons orbiting the nucleus. Explaining the behavior of these electron "orbits" was a key issue in the development of quantum mechanics.
The electron cloud model says that we cannot know exactly where an electron is at any given time, but the electrons are more likely to be in specific areas. These areas are specified by orbitals. The orbitals are specified by shells and sub-orbitals. In the Bohr model, electrons are assigned to different shells. The shells, k,l,m,n,o,p,q, each represent different levels of energy, and are also called energy levels. The sub-orbitals; s,p,d,f, are regions where it will be more likely to find electrons, and can each hold a different number of electrons. the s,p,d,f orbitals are all shaped differently. This can be proven by the repeating patterns of chemical properties in the periodic table. Using quantum mechanics, chemists can use the electron cloud model to assign electrons to different atomic orbitals. Atomic orbitals also explain the patterns in the periodic table.

Electron cloud is an informal way to describe an atomic orbital. The electron cloud model says that we cannot know exactly where an electron is at any given time, but the electrons are more likely to be in specific areas.
Explanation:
- An electron cloud is the region of negative charge surrounding an atomic nucleus that is associated with an atomic orbital.
- It is defined mathematically, describing a region with a high probability of containing electrons.
- The electrons move from negatively charged parts to positively charged ones.
- The negatively charged pieces of any circuit have extra electrons, while the positively charged pieces want more electrons.
- The electrons then jump from one area to another. When the electrons move, the current can flow through the system.
