Why do the alkali metals occupy Group 1

Explanation:

Alkali metals occupy Group 1 because;

They are all soft, highly reactive electropositive metals. These metals, along with francium, occupy the far left group of the periodic table, group 1. They have greater shielding from the inner electrons as the group is descended makes ionisation of the atoms easier, increasing the reactivity.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
