Boron's atomic number is 5. Thus, it has 5 protons per atom. To be electrically neutral then, it must also have 5 electrons per atom.
Boron has five(5) electrons. they are arranged in two energy shells. The innermost shell ( nearest the atomic nucleus), contains two electrons , that do NOT combine with other atoms. The outermost energy shell (furthest from the atomic nucleus), contains the remaining three electrons. These three electrons are the valence electrons , and form bonds with three other atoms.
Boron has 5 electrons in total.
Boron has three valance electrons. Boron also has three electtrons in outermost energy shell. The 'Valance' number of electrons tells you how many bonds will form between boron and other atoms. Compare with oxygen . Oxygen has two valance electrons . However, oxygen has 6 electrons in its outermost energy shell. This means that oxygen will form two bonds between other atoms. Thus leaving four electrons uncombined; they are known as 'lone pairs'.
No atom has its electrons in its nucleus, and boron has five electrons around its nucleus.
