It's in group 1, so its outershell only has 1 electron, and the other shells are completely filled, so 2 then 8. :)

Answer:
The formula for the anhydrous compound that was part of the mixture called natron that was used by the Egyptians is Na2(CO3)10(H2O).
They use this compound for medicine, cookery, agriculture, in glass-making and to dehydrate egyptian mummies.
Compound of sodium carbonate and sodium bicarbonate was the name of the resulting hydrate that formed.
Lithium sulfate is Li2SO4
Strontium chlorate is Sr(ClO3)2
Strontium sulfate is SrSO4
So the complete balanced chemical reaction for this is:
Li2SO4 (aq) + Sr(ClO3)2
(aq) --> SrSO4 (s) + 2 LiClO3
(aq)
This is a type of double replacement reaction since there
is an exchange of ions.
