Why halogens are so reactive?
Halogens are highly reactive, and they canbe harmful or lethal to biological organisms in sufficientquantities. This reactivity is due to high electronegativityand high effective nuclear charge. Halogens can gain anelectron by reacting with atoms of other elements. Fluorine is oneof the most reactive elements.Are halogens reactive?
The halogens are all elements that are found ingroup 17 of the periodic table. The halogens includefluorine, chlorine, bromine, iodine, and astatine. All of theseelements are considered to be reactive nonmetals. Becausethese atoms are so close to having a full set of eight valenceelectrons, they're very reactive.What is Group 8 called?

Metallic calcium was first isolated by SirHumphry Davy in 1808 through the electrolysis of a mixture of lime(CaO) and mercuric oxide (HgO). Today, metallic calcium isobtained by displacing calcium atoms in lime with atomsof aluminum in hot, low-pressure containers.Why is calcium so reactive?
Having more shells, mean that the attraction from thenuclues will be smaller, because it has more shells to hold inplace. So with calcium having more shells, it iseasier for it to react or lose electrons than the magnesium. Whycalcium is more reactive than magnesium thoughmagnesium is up in reactive series?
