The number of atoms present in a molecule determines its _.
Correct answer: D. Atomicity
- A. Shape
- B. Size
- C. Molecularity
- D. Atomicity
Explanation
Correct option is D. Atomicity is defined as the number of atoms in the molecules of an element. Atomicity refers to the number of atoms present in a single molecule of an element, substance or compound. It can also be considered as the nature of molecules. According to the atomicity of a substance, it can be Mono, Di, Tri or Polyatomic. For example, oxygen or O2 is diatomic because it has 2 atoms in its molecule.

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.
