5 electrons
The correct answer to this question is in fact 7 electrons not 5. See attached link.

4V V-Valence Electrons Valence Electrons-Last electron (which is on the outer shell)
The outer shell (N=4) of the copper element has 2 electrons.
Boron has 5 electrons per atom. Boron's electron configuration is 1s2 2s2 2p1. Thus, it has 3 electrons in its outer shell.
14
it has 6 electrons in the outer most shell
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Nitrogen has 5 electrons in its outer shell, and Bromine has 7 electrons in its outer shell.
7
seven it has to be
Seven , outer shell electrons or valence electrons increase as you move from left to right on the periodic table not including the transition metals which vary, they start with 1 valence in the alkali earth metals , and finish with 8 valence electrons on the noble gasses (group 18)
Bromine has 7 electrons in it's outer shell. It can hold eight so, it needs 1 more electron. The answer above is is probably the answer expected, however as the the question says outer shell which sometimes is used to refer to the highest principal quantum number, in bromines case 4, the answer could be 25, as the fourth shell can hold 32 electrons.
Calcium has two electrons in the outer shell.
Vanadium has on the outer shell two electrons.
Boron has three electrons in its outer shell
8 electrons on the outer shell
2 outer shell electrons
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
