In the modern periodic table, Elements are arranged in increasing order of their atomic numbers.
Vertical columns are called groups. There are 18 groups. The chemical properties of the elements in the same group show similarity and gradation.
Horizontal rows are called periods. There are in all 7 periods. The properties of elements change slowly from one end to the other in a period.

Arrangement of Elements in the Modern Periodic Table
Elements in the Modern Periodic Table are arranged in increasing order of their atomic number. This is the key principle behind the arrangement of elements in the Periodic Table.
Importance of Atomic Number
- The atomic number of an element is defined as the number of protons in the nucleus of an atom of that element.
- It uniquely identifies an element as each element has a distinct atomic number.
Reasons for Arranging Elements by Atomic Number
- The arrangement by atomic number helps in grouping elements with similar chemical properties together.
- It also helps in establishing a clear trend in the properties of elements across periods and groups in the Periodic Table.
- The atomic number gives a more accurate reflection of an element's properties compared to atomic mass, which might vary due to the presence of isotopes.
Historical Perspective
- Initially, elements were arranged by increasing atomic mass, but this led to inconsistencies and anomalies in the properties of elements.
- The discovery of isotopes and advancements in atomic theory necessitated a shift to the current arrangement by atomic number.
Conclusion
In conclusion, the arrangement of elements in the Modern Periodic Table by increasing atomic number is a fundamental principle that underpins the organization of the elements based on their properties and relationships. This systematic arrangement has greatly contributed to our understanding of the behavior of elements and their compounds.
