2 electrons.
Strontium's atomic number is 38. So, it has 38 protons and 38 electrons if it's neutral. Strontium is a group 2 element and so has 2 valence electrons. Thus, the rest of the 36 electrons are core electrons.
Vanadium has on the outer shell two electrons.
2 outer shell electrons

Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Boron has three electrons in its outer shell
8 electrons on the outer shell
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
2 outer shell electrons
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
There are different electrons in the outer shell of each element.
