What is the atomicity of cobalt
Answers
Answer:
The atomicity of cobalt is 3.
Answer:
Atomicity is defined as the total number of atoms that constitute a molecule. For example, each molecule of oxygen (O2) is composed of two oxygen atoms. So atomicity of oxygen is 2.[1]In older contexts, atomicity is sometimes synonymous with valency.
On the basis of atomicity, molecules can be classified as :
Monoatomic-composed of 1 atom e.g. He, Ne, Ar (all noble gases are monoatomic)
Diatomic-composed of 2 atoms e.g. H2 , N2 , O2
Triatomic-composed of 3 atoms e.g. O3
Tetraatomic-composed of 4 atoms e.g. P4
Polyatomic-composed of 4 or more atoms e.g. P4 , S8
All metals and some other elements, such as carbon, do not have a simple structure but consist of a very large and indefinite number of atoms bonded together. Their atomicity cannot be determined and is usually considered as 1.
Atomicity may vary in different allotropes of the same element.
The atomicity of the first 20 elements in the periodic table is as follows:
