How Many Electrons Does Boron Have?

Boron is atomic number 5 on the periodic table of elements, which means it has five protons and five electrons. More than 99 percent of natural boron exists as the isotopes boron-10 and boron-11, which means boron usually has five or six neutrons.

Boron does not exist as a free element in nature, but it is common in chemical compounds such as borax, which is a component of household detergents. The main source of boron is the mineral rasorite, which is found in the Mojave Desert in the United States. Turkey also has a large amount of boron reserves.

Boron is an important nutrient for plants. It is used in the nuclear industry and in the production of semiconductors and magnets.
