Boron is a chemical element, and an industrial gas with symbol B. In its elemental form, it has two stable isotopes. It is a diamond-white color in the oxidation state of +3 and is never found in nature as a pure element.

What is the Electronic Configuration of Boron?

electron configuration of boron

Long Form

In long form, the electronic configuration of boron is 1s2 2s2 2p1. This means that there are two electrons in the 1s orbital, two in the 2s orbital, and one in the 2p orbital. The 1s and 2s orbitals are filled before the 2p orbital is filled.

Short Form

The electronic configuration of boron is 1s2 2s2 2p1. The outermost energy level of boron (the 2p level) only has one electron in it. This means that boron is less stable than other elements with similar configurations. When boron atoms form bonds with other atoms, they often do so by sharing their single outermost electron with another atom. This gives boron a tendency to form bonds with other atoms in which the boron atom has an unpaired electron.

Diagram of Ground State and Excited State

The electronic configuration of boron in its ground state is 1s2 2s2 2p1. The diagram below shows the orbitals involved in this configuration. The excited state is generated by promoting one electron from the 2s orbital to the 2p orbital. The resulting configuration is 1s2 2s1 2p2.

The shapes of the s and p orbitals are shown in the figure below. The s orbitals are spherical, while the p orbitals are dumbbell-shaped. In the ground state, both orbitals are filled with two electrons. In the excited state, one electron is promoted from the s orbital to the p orbital.

The energy levels of these orbitals are also shown in the figure. The energy of the s orbitals is lower than that of the p orbitals. This is why electrons occupy these orbitals in the ground state. When an electron is promoted to a higher energy level, it is said to be in an excited state.

Ground State: Unabbreviated

ground state of boron

In quantum mechanics, the ground state of a system is its lowest-energy state; the energy of the ground state is known as the zero-point energy. An atom in its ground state has electrons occupying the lowest possible orbits around the nucleus. The term “ground state” can also refer to the lowest energy state of an atomic nucleus, an ion, or a molecule.

Ground State: Abbreviated

In chemistry, the ground state of an atom is its lowest-energy state. The term “ground state” can also refer to the lowest energy state of an atomic nucleus, an ion, or a molecule.

When an atom or molecule is in its ground state, it is said to be “stable.” This means that it is not undergoing any sort of chemical reaction, and it is not absorbing or emitting any form of energy (including light).

The electronic configuration of boron in its ground state is 1s2 2s2 2p1.. This means that the boron atom has two electrons in its first shell (the 1s orbital), four electrons in its second shell (the 2s and 2p orbitals), and one electron in its third shell (the 2p orbital).

Excited States: Unabbreviated

In an excited state, an atom is raised to a higher energy level by either absorbing or emitting a photon. The energy of the photon must match the energy difference between the two levels. When an electron is excited from the ground state to a higher energy level, it is said to be in an “unabbreviated” excited state.

Excited States: Abbreviated

In chemistry, an excited state is an elevated energy level within an atom, molecule or ion. The term may refer to an electronic, atomic or nuclear configuration, or a particular energy level of an electron in an orbital.
Boron has five electrons in its ground state, so its electronic configuration is 1s2 2s2 2p1. When it is in an excited state, one of the 2s electrons is promoted to a 2p orbital, and its configuration becomes 1s2 2s1 2p2.
