Chemistry
The number of atoms of the same type which combine to form a molecule of an element is called its :
- Atomicity
- Valency
- Molecular formula
- Compound
Answer
Atomicity
Reason — The number of atoms of an element that join together to form a molecule of that element is known as the atomicity of that molecule.
Valency is the combining capacity of an element or of a radical. A compound is a pure substance formed by the chemical combination of two or more elements in a fixed ratio by mass. The molecular formula of an element is the symbolic representation of its molecule. It indicates the number of atoms present in it.
