The total number of valence electrons in Boron's ground state is 2
Boron has 3 valence electrons out of five total electrons.
3
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.
Boron has 3 valence electrons.Boron has 3 valence electrons.
A boron atom has 5 electrons and three of them are located in the valence shell.
Boron has 3 valence electrons out of five total electrons.

Boron has 3 valence electrons.Boron has 3 valence electrons.
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.
A boron atom has 5 electrons and three of them are located in the valence shell.
Boron has 3 valence electrons.
Boron has 3 valence electrons.
Boron has three valence electrons.
A fluorine atom in the ground state has 7 valence electrons.
Selenium would not have the same number of valence electrons as the others. Boron, aluminum, and gallium all have 3 valence electrons, while selenium has 6 valence electrons.
Boron family is group IIIA so 3 electrons are in the outermost shell.
