How many electrons do the alkali metals have in their outer energy shell?

If you are referring to the alkali metals of Group 1, such as sodium and potassium, the answer is no - in fact with a valence of 1 they are short 7 electrons in their outer level, which is why they react so readily (and violently) with the halogens, chlorine, fluorine and so on.

∙ 8y agoNo, they all have 2 electrons in it when in elemental (atomic) form. That's for alkali earth elements. Alkali metals have one 1 electron in the outer most shell.

The external shell contain only one electron.

Elements with one to two electrons in the outer energy level?
Alkali and alkaline earth metals
Hydrogen is grouped with alkali metals because it?
it has one electron in its outer energy level like all alkali metals
What is the difference between alkali metals and alkali earth metals?
Alkali metals are from Group 1 of the Periodic table and have a single electron in their outer shell. Alkaline-Earth metals are in group 2 of the periodic table and have 2 electrons in their outer shell.
Does alkali metals have a full outer energy level?
No, they don't.
How many valence electrons alkali metals have?
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.
What is the name of metals with two electrons in the outer energy level?
You think probable to alkali earth metals.
Elements with one to two electrons in the outer energy level?
Alkali and alkaline earth metals
What element with 1-2 electrons in the outer energy level?
Hydrogen, helium, alkali, alkaline metals.
How many outer electrons are in alkali earth metals?
Two!
Hydrogen is grouped with alkali metals because it?
it has one electron in its outer energy level like all alkali metals
How many electrons are in the outer energy level of the atoms of alkali earth metals?
There are two electrons on the outer shell which means they are pretty reactive. (make bonding easier)
Does alkali metals have a full outer energy level?
No, they don't.

Which group metals are very reactive with one electron in the outer energy level?
Alkali metals
How many electrons are in the outer energy level of an atom of each of the alkali metals?
this is a very easy question...the answer is the symbols be,mg,ca, and Sr on the periodic chart
Do alkali metals have a full outer energy level?
Nope. They sure don't.
