Answer: Boron has 3 valence electrons.
The total number of electrons that are present in the last shell of any element is called the valence electrons of the boron. The valence electrons is equally responsible for the determination of the properties of the element. They participate in the formation of bonds and thus are essential for any element. To identify the valence electrons in any element, it is important to determine electron configuration. By knowing the electron configuration, it is possible to identify the valence electron of any element. Other than this, it is also possible to identify the valence electron by arranging electrons according to the Bohr principle.
To identify the number of valence electrons or protons in any element, it is important to understand the complete formation of the element. In an element, the nucleus is at the center of an atom and the neutrons and protons are located inside the nucleus.
How many valence electrons are present in boron?
Boron has 3 valence electrons. The valence electron in any element can be said as a total number of electrons that is present in the last orbit. The valence electron or the number of electron in the outer shell or orbit of the boron is 3.
