Alkali metals are gp1 while halogen gp
prera:
Gp7 ... Alkali have 1 valence electron and halogen have 7 valence electrons.... Alkali metals are more reactive down the gp and halogens are less reactive down the gp
Sorry I m new to this app so not able to use properly but trying the best:-)
yes its true trie u best to achieve u target may good bless u

Alkali metals
1. Alkali metals have less density compared to other metals.
2.They have loosely bound valence electron.
3.They contain large radii in the periods.
4.They have low ionization energy and electronegativity.
5.They are highly reactive in nature.
Halogens
1.These are high reactive elements in the group and have high electron affinity.
2.They have low dissociation energy which means they can dissociate very easily to combine with other substances.
3.They are highly volatile and are readily reacted with alkali metals and alkaline earth metals.
4.Halogens readily react with hydrogen to form hydrogen halides as binary compounds.
