(a) Interpretation: The more basic oxide between Cr 2 O 3 or CrO needs to be determined. Concept introduction: All known elements are placed in the periodic table. Here the elements are arranged in increasing order of their atomic number . There are 18 vertical columns and 7 horizontal rows which are called as period. And the vertical columns are called as groups. The entire table can be divided into metals, non-metals and metalloids. Metals are placed at the left side of the periodic table and exhibit several different chemical and physical properties compare to non-metals which are placed at the right side of the periodic table.

Solution Summary: The author explains that all known elements are placed in the periodic table. Metals, non-metals, and metalloids exhibit chemical and physical properties.
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.
