   What is periodic table in chemistry?

   • Periodic table, in chemistry, the organized array of all the chemical elements in order of increasing atomic number. When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties.

   How are elements organized on the periodic table?

   • The original table organized the elements by increasing atomic weight. Each horizontal row on the periodic table is called a period. There are seven periods on the periodic table. Elements in the same period all have the same electron ground state energy level.

   How does the organization of the periodic table work?

   • The organization of the periodic table allows you to predict the properties of the elements based on their position on the chart. Here's how it works: Elements are listed in numerical order by atomic number. The atomic number is the number of protons in an atom of that element. So element number 1 (hydrogen) is the first element.

   Why is the periodic table arranged in order?

   • The important point to note is that although the modern periodic table is arranged in order of increasing number of protons and electrons, the repetition and patterns that emerge are the property of the electrons, their arrangements, and energies. This is our next subject. Science fiction authors like weird elements.

   Although John Dalton produced a table of elements with their atomic weights in 1805, it was only when Dimitri Mendeleev (1834–1907) tried to organize the elements in terms of their chemical and physical properties that some semblance of order began to emerge.
