The answer is: The overall charge of the electron cloud is negative,
Electron: Electron is a sub-atomic particle which is found outside the nucleus of an atom. The charge carried by an electron is negative.
What is the electron cloud and who suggest this idea?
- Erwin Schrödinger developed electron cloud model.
- He suggested that atoms have a central nucleus made up of protons and neutrons. Around it is the "probability region" where electrons are most likely to be found.
- The higher the density, the more likely the electron will be found in this region.
- This dense probability region is called an electron cloud.
- As this region carries only negatively charged electrons, thus the overall charge of the electron cloud is negative.
