Ion for boron
WebBoron is essential for the cell walls of plants. It is not considered poisonous to animals, but in higher doses it can upset the body’s metabolism. We take in about 2 milligrams of … WebBoron leaves three electrons and turns into a positive ion. Therefore, boron is a cation element. B – 3e – → B 3+ The electron configuration of boron ion (B +3) is 1s 2. This electron configuration shows that boron ion (B +3) has only one shell and that shell has a total of two electrons.
