प्रश्न
Explain the following:
Group 17 elements are strong non-metals, while group 1 elements are strong metals.
उत्तर
On moving across a period, nuclear pull increases because of the increase in atomic number, and thus, the atomic size decreases. Hence, elements cannot lose electrons easily. Hence, Group 17 elements are strong non-metals, while Group 1 elements are strong metals.
