why are group VII A elements very reactive non metals
Answers
Answer:
Group VII A elements are very reactive non metals because they need only one electron to fulfill their noble gas configuration. ... They will steal electrons from where ever they can to get that configuration. They are also very electronegative due to the increased effective nuclear charge compared to other elements.

Answer:
Group VII A elements are reactive non-metals as the electronegativity of group VII A elements is comparatively high. The size of atom is comparatively smaller than other atoms, hence the attraction power of the nucleus is much more greater, resulting them in attracting electrons, and they are thus classified as highly reactive non-metals.
Explanation:
Halogens are a number of the most active nonmetals because of their electron configuration and number of valence electrons. Electrons are the negatively charged particles that orbit the nucleus of an atom in numerous energy levels. The electrons withinside the outermost stage are called 'valence electrons'. Valence electrons are involved in bonding, and maximum atoms need 8 valence electrons with a view to be stable with a complete outer shell. As we pass down a group the reactivity of non-metals decrease. This is because :
- The number of valence shells gradually increases.
- The force with which the nucleus holds the electrons decreases and thus furthermore the tendency to lose electrons increases.
- Since non metals gain electrons to shape a totally filled outermost shell, the reactivity decreases.
