(a) Interpretation: The group in the main group of elements that contains no metals or metalloids needs to be identified from the given options. Concept introduction: The periodic table of elements provides a means to classify various atoms based on their atomic number . The elements are arranged from left to right across rows in the periodic table in the order of increasing atomic number. In addition, elements with similar properties are placed in vertical groups or families. These groups are classified as metals (good conductors of heat and electricity), non-metals (non-conductors) and metalloids (properties in between metals and non-metals)

Solution Summary: The author explains that the periodic table of elements provides a means to classify various atoms based on their atomic number.
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.
