How many electrons in the outer valence shell of calcium?
There are 2 electrons in valence shell of calcium. :-)
How many electrons in the valence shell of a silicon atom?
A silicon atom has 4 electrons in its valence shell.
How many electrons are there in the valence shell of a nitrogen atom?
Nitrogen has 5 valence electrons. Its atomic number is 7 therefore it has a total of 7 electrons. If you put this in a Bohr-Rutherford Diagram, there would be 2 electrons in the first shell (Helium structure) and 5 electrons in the outer shell. The number of electrons in an element's outermost shell is its number of valence electrons.

How many electrons does francium have in its outer most shell?
Well, darling, francium is a wild child with only one electron in its outermost shell. It's living life on the edge, ready to jump into any chemical reaction that comes its way. Just one electron, but oh boy, does it make a splash!
