What is the atomicity of an element?

The atomicity of an element refers to the number of atoms present in a single molecule of that element. For example, oxygen has an atomicity of 2 because its molecule contains 2 oxygen atoms (O2), while helium has an atomicity of 1 since it exists as single atoms (He).

What formula is used to calculate the atomicity of elements?

The atomicity of an element is determined by its tendency to form molecules and is related to the number of atoms that make up a molecule of that element. It is not calculated using a formula but can be determined based on the chemical structure of the element or compound. For example, diatomic elements like oxygen (O2) have an atomicity of 2, while monoatomic elements like helium (He) have an atomicity of 1.


How can you find the atomicity of any element?

The number of atoms constituting a molecule is known as its atomicity. On the basis of atoms present in that particular element we can find out the atomicity. To find the atomicity you should know the valency of that atom. Try to remember the atomic number of the elements in the periodic table. From this you can easily find out the electronic configuration and hence the valency.


What is the atomicity of mercury?

Mercury is a chemical element with an atomic number of 80, which means it has 80 protons in its nucleus. This gives it an atomicity of 1, since it is a single atom by itself.
