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 valence electrons have boron have?
3 valence electrons. As the atomic number of boron is 5, it would have 2 electrons in the first shell and 3 valence electrons in the second shell.
