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'.
im not sure but i thinks it's three
3 valence electronsThere are three valance electrons. These are the electrons in the outer shell if it is not full.
If you are talking about the valance electrons any elements in group 5 on the periodic table will have 5 valance electrons.
Boron's atomic number is 5. Thus, its electron configuration is 1s2 2s2 2p1. If you add up the number of electrons in the "2" shell, which is boron's valence shell, you get 2 + 1 = 3 valence electrons.
