An orbital is also called as:
Correct answer: A. Electron cloud
- A. Electron cloud
- B. Electron sea
- C. Sub-shell
- D. Sub-level
Explanation
An electron cloud can be thought of as a probability field, the area in space where an electron is likely to be. In an atom, these fields, specific regions of space where an electron most likely hangs out, are called orbitals.Orbitals are often referred to as "electron clouds" because they describe the three-dimensional probability distributions of where electrons are likely to be found within an atom.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
