the halogens increase with the increase in their reactivity and scientific name and atomic mass
Sck:
pls give in brief
ok I will
Halogens are nonmetals in group 17 (or VII) of the periodic table. Down the group, atom size increases. As a diatomic molecule, fluorine has the weakest bond due to repulsion between electrons of the small atoms.. the main reason is because of their reactivity. hope this was helpful
yes
thank u so much
