alkali metals have 1 electron in there outer valence shell. I remember that alkali and alkaline go with columns 1 & 2 of the periodic table alphabetically. Alkali then alkaline. Alkali metals have 1 valence electron. Alkaline metals have 2 valence electrons.
There are no unpaired electrons in strontium.
one valence electrons

There are many elements which have no unpaired electrons in their outer shells. The Noble gasses all have closed shells of valence electrons. The alkali earth metals (Beryllium, Magnesium, Calcium etc) also have no unpaired electrons, although their outer shell is not entirely full.
1 valence electron in alkali metals.

Yes , It has four

Alkali metals have one electron more than the noble gases.
There are 3 unpaired electrons.
zero - there are no unpaired electrons
three unpaired electrons
There are no unpaired electrons in strontium.
