Group VII elements are strong non metals, while group I elements are strong metals. Explain.

Solution

While moving across the periodic table the nuclear pull increases because of this increase the atomic size decreases.
Hence, Group VII elements are strong non-metals because they can accept electrons while group I elements are strong metals because they can donate electrons.

Q. Explain:
(i) Larger the atomic size, more metallic is the element.
(ii) Halogens have high electron affinity.
(iii) Size of atom changes when it loses or gain electron.
(iv) K is more reactive than Li.
(v) Electronegativity of Cl is higher than S.
(vi) Group 17 elements are non-metals, while group 1 elements are metals.

Q. Which group elements are the most reactive among the non-metals?

233. Group VII elements are strong non-metals because they can easily accept an electron to form an anion whereas group I elements are strong metals because they can very easily lose one electron to form a cation. Metals have the tendency to lose their valence electrons and form positive ions, so metallic character is related to the ionization potential. Elements having low ionization potential, lose easily. Thus, a metallic character generally decreases across a period and increases down a group.

Group 1 and Group 2 elements are considered strong metals because
