How many electrons does francium have in its outer most shell?
francium only has one valence electron (one electron in the outermost shell).
How many electrons in the outer valence shell of calcium?
There are 2 electrons in valence shell of calcium. :-)
How many electrons are in the valence shell of all column 1 elements?
there are 36 electrons in a valence shell. -cmoney
How many electrons would be present in the valence shell of a iron atom?
Valence electrons are the total amount of electrons on the outermost shell of an atom. Meaning if the last shell has two, the valence electrons are two. But a complete valence shell would hold eight.
How many more valence electrons does magnesium need to have a full outer valence shell?
it needs six more electrons to have a full outer 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.
