For the quintessence of classical philosophy, see Aether (classical element). Boron is a chemical element with symbol B and atomic number 5. Produced entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis, it is a low-abundance element in the Solar system and in the Earth's crust.
We represent the arrangement of electrons in an atom (the electron configuration) using an orbital diagram, a picture that shows the arrangement by orbital. A sample orbital diagram for the boron atom is shown below. Boron has five protons and five electrons.2s 2 2p 1). The two electrons in boron's 1s orbital (1s 2) are buried too deep inside the atom to react. You might be wondering at this point how you write an electron configuration-how to determine the order that orbitals fill up in.
