Boron has three electrons in its outer shell
An atom of boron has 3 paired electrons. Boron has 5 electrons in its neutral state, with 2 electrons in the first shell and 3 paired electrons in the second shell.
3 valence electrons. As the atomic number of boron is 5, it would have 2 electrons in the first shell and 3 valence electrons in the second shell.
There are three electrons in boron's outer energy level.

Boron has two orbital shells. The first shell contains 2 electrons, while the second shell can hold up to 8 electrons. Boron typically has 5 electrons, with 2 in the first shell and 3 in the second shell.
Boron has 5 electrons per atom. Boron's electron configuration is 1s2 2s2 2p1. Thus, it has 3 electrons in its outer shell.
Boron has 3 electrons in the outer shell and 2 electrons in the inner.
Boron has 2 orbitals
Innermost is surely 2, as with every atom apart from Hydrogen?
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.
3 valence electronsThere are three valance electrons. These are the electrons in the outer shell if it is not full.
