There are three valance electrons. These are the electrons in the outer shell if it is not full.

Four.
14 total electrons. 5 valence electrons.
Hydrogen only has 1 electron.
Boron has 3 valence electrons.
Boron has 3 valence electrons.
Boron has 3 valence electrons.
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'.

3, the electron configuration of Boron is 1s2 2s2 2p1, so there are 3 in the outer shell.
3 valence electronsThere are three valance electrons. These are the electrons in the outer shell if it is not full.
