Alkali Metals (Here-Potassium)
less dense than other metals
one loosely bound valence electron
highly reactive, with reactivity increasing moving down the group
largest atomic radius of elements in their period
low ionization energy
low electronegativity
Alkaline Earth Metals(Calcium/magnesium)
two electrons in the valence shell
readily form divalent cations
low electron affinity
low electronegativity
The halogens and noble gases are nonmetals, although they have their own groups, too.
high ionization energy
high electronegativity
poor electrical and thermal conductors
form brittle solids
little if any metallic luster
readily gain electrons

Not in a group but in groups, that's to say separate groups..
Ok I am editing the answer till then mark me as brainiest
