Question

() Which element of group IA is not an alkali metal and why?​

Answer 1

${\huge {\underline {\mathcal {❥} \red {A} \blue {n} \green {s} \orange {w} \pink {e} \purple {r}}}}$

Explanation:

Hydrogen is not an alkali metal itself, but has some similar properties due to its simple one proton (loctated in the nucleus), one electron arrangement. The lone electron exists in a s -orbital around the nucleus. For lithium, there are two 1 s electrons in an inner orbit and one 2 s electron in the outer orbit.

Answer 2

Answer:

They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). (Like the other elements in Group 1, hydrogen (H) has one electron in its outermost shell, but it is not classed as an alkali metal since it is not a metal but a gas at room temperature.)
