GENERAL KNOWLEDGE

Detailed explanation-1: -In a periodic table arranged in order of increasing atomic number, elements having similar chemical properties naturally line up in the same column (group).

Detailed explanation-2: -A modern periodic table arranges the elements in increasing order of their atomic numbers and groups atoms with similar properties in the same vertical column (Figure 2). Each box represents an element and contains its atomic number, symbol, average atomic mass, and (sometimes) name.

Detailed explanation-3: -What is the periodic table? The periodic table is a tabular array of the chemical elements organized by atomic number, from the element with the lowest atomic number, hydrogen, to the element with the highest atomic number, oganesson.

Detailed explanation-4: -Mendeleev’s periodic table is an arrangement of elements in an increasing atomic mass order in a tabular form, such that it reflects similarities and trends in the behavior of elements.

Detailed explanation-5: -Scientists have organized the elements into a table based on their properties. This table is called the Periodic Table. Dimitri Mendeleev, a Russian scientist, is credited with the creation of the Periodic Table. Mendeleev based his arrangement of elements on both increasing atomic mass and similar properties.
