The group of the element M in the periodic table should be identified. Concept Introduction : The elements are arranged in periodic table as increasing order of atomic number . The molecular formula of a compound can be used to determine the group number of the element. The number of electrons is shared and transfer for the formation of compounds such that all the atoms have complete octet.

Solution Summary: The author explains that the molecular formula of a compound can be used to determine the group number of the element.
Definition Definition Number of protons in the nucleus of an atom. It uniquely identifies an element, as the number of protons determines the element's properties. The periodic table of elements is arranged based on increasing atomic numbers, allowing scientists to easily locate and study elements.
