Concept explainers
The number of types of atoms that can beexpected to be found in a pure sample of any element.
Introduction:
Every matter is made up of atoms.Atom is the elementary composition of matter. Chemical elements are the pure substance. Due to unique electronic configuration, these elements show different chemical and physical properties.
Explanation:
Presently, there are 118 chemical elementsknown to exist. Around 20% of them are not natural elements as they areprepared in laboratory. First element formedwas the hydrogen. Elements are the building blocks for the all matter in the universe. Two different elements combine together to form compound which is totally different from the elements through which it is made. In compound, elements lose its identity. Elements consist of same atoms. Due to their similar chemical and physical properties, they are identical in nature. Number of outermostelectrons in the different elements are distinct. Uniqueness of chemical and physical properties of different elements arebecause of the different placement of the electrons inside the atom.Therefore, in pure element only one type of atoms is present which gives rise to the unique physical and chemical properties to that element.
Conclusion:
Therefore, pure element has only one type of atoms.
