Number of Atoms present in Molecule of Element

In the H2O molecule, As it contains two triatomic hydrogen molecules and one triatomic oxygen molecule, the molecule has three atomicities. In O2, As it contains two diatomic oxygen molecules, its atomicity is 2.

• The number of protons in the nucleus of an atom is known as the atomic number.
• A substance’s molecular mass is calculated by adding the atomic masses of all the atoms that make up the molecule.
• Atomic mass: An atom’s atomic mass is its whole weight.

The smallest unit of matter that may be divided without producing electrically charged particles is the atom. It is also the smallest piece of substance with chemical element-like characteristics. As a result, the atom serves as the fundamental unit of chemistry.

Space makes up the majority of an atom. The rest is made up of a cloud of negatively charged electrons surrounding a positively charged nucleus made up of protons and neutrons. Compared to electrons, which are the lightest charged particles in nature, the nucleus is small and dense. Electric forces, which link electrons to the nucleus of atoms, causing them to be drawn to any positive charge.

Summary:

The number of atoms present in the molecule of an element is known as its – (a) Atomic number (b) Molecular mass (c) Atomicity (d) Atomic mass

The atomicity of an element refers to how many atoms are included in a molecule. A molecule is made up of two or more atoms, which are the smallest unit of matter.
