List of Elements of the Periodic Table

A brief study of the elements in Mendeleev’s periodic table. The article includes the types of elements per the periodic classification and their names.

Have you ever pondered that the oxygen you breathe, the different automobile parts, the ornaments you use, and computer semiconductors are all made up of various elements? The modern periodic chart, which is concerned with the study of the environment around us, has roughly 118 elements. These elements are arranged in a tabular form in the periodic table. Approximately 31 chemical elements were found around 1800. In 1865, a total of 63 new elements were discovered. The periodic classification of elements became vital as a result. What are the elements? Let’s find out more in the brief study of the periodic table. 

The Periodic Table: What is it?

The periodic table is a list of chemical elements arranged in a table. It is arranged in ascending atomic number order. In their properties, there is a repeated pattern known as the “periodic law,” in which members in the very same column (group) exhibit comparable properties. Metals are to the left in one row (period), while non-metals are to the right. The elements that have similar chemical characteristics are grouped in the same column.

Mendeleev’s Periodic Law

Mendeleev’s Periodic Law states that the chemical and physical properties of elements are the periodic functions of the elements’ atomic weight. 

Dmitri I. Mendeleev, a Russian chemist, made the first significant and notable contribution to element classification in 1869. He developed the Periodic law based on his extensive research on the periodicity of physical and chemical properties of elements. He noticed the periodicity when the elements were positioned according to their atomic weights. 

The periodic table organised the vast quantity of information accessible for each element. At the time of Mendeleev, only 63 elements were known. These elements were arranged in the periodic table as per their atomic weights. 

Features of the Periodic Table

Mendeleev’s Periodic Table has the following main characteristics:

  • The items in this table are organised together in vertical columns named groups. The horizontal rows are called periods.
  • I, II, III, IV, V, VI, VII, VIII, and 0 are the nine groupings identified by Roman numbers. The elements in the first seven groups have been separated into two subgroups, A and B, based on their similar qualities. 
  • Subgroup A comprises items on the left side of each group, while subgroup B is made up of elements on the right side. 
  • Group VIII is made up of nine elements organised in triads. The elements in the zero group belong to the inert gas family and have zero valencies.
  • There are seven distinct periods. They are numbered from. 1 to 7. The 4,5,6 and 7 numbered periods are split into two halves to allow more elements. In each box, the first portion of the elements is located in the top left corner, while the second half is placed in the lower right corner.
  • The shortest period is the first one with only two elements. Short periods are the second and third periods, each of which has eight elements. Long periods have eight elements each and are classified as such by the 4th and 5th categories. The 6th period, which has 32 elements, is considered the longest. As the elements are included in this period, the last period, i.e. the 7th period, is incomplete.

Periodic Table Classification

The periodic table classification includes different types of elements in the modern periodic table. The elements are segregated into:

  • Noble gases
  • Transition elements
  • Non-metals
  • Metals
  • Inner transition elements
  • Main group elements
  • Metalloids

Conclusion

Dmitri Mendeleev, a Russian chemist’s periodic table, was the first to gain widespread acceptance in 1869. Mendeleev created a table called Mendeleev’s periodic table. It contained all the 63 elements known during his time. The elements were placed horizontally in Mendeleev’s periodic table in order of increasing atomic weights. The above article concerns all the 118 elements positioned in the periodic table according to their atomic weights.
