What Is Electron Configuration?

Electron configuration refers to the arrangement of electrons within an atom. Specifically, it describes how electrons are distributed across the various orbitals (energy levels) of an atom’s electrons. Put simply, it tells us how many electrons an atom has and how those electrons are arranged.

Explanation Of Electron Configuration

The electron configuration of an atom is determined by a set of three quantum numbers that describe the energy and position of each electron within the atom. The first number, called the principal quantum number (n), describes the energy level of the electron; the second number, known as the angular momentum quantum number (l), describes the shape of the electron’s orbital; and the third number, called the magnetic quantum number (m), describes the orientation of the electron’s orbital within space.

Energy Level (n) Number of Electrons Example
1 2 Helium (He): 1s2
2 8 Neon (Ne): 1s2 2s2 2p6
3 18 Argon (Ar): 1s2 2s2 2p6 3s2 3p6

As shown in the table above, the electron configuration of an atom is typically written using a series of numbers and letters that describe the number of electrons in each energy level and the orbitals those electrons occupy. For example, the electron configuration of helium (He) is 1s2, which means it has two electrons in the first energy level (n=1) and both of those electrons occupy the s-orbital (l=0).

Importance Of Electron Configuration

Understanding electron configuration is essential to understanding the chemical and physical properties of elements. This is because the way in which electrons are arranged within an atom directly affects how that atom will interact with other atoms. For example, atoms with a full outer shell of electrons (like noble gases) tend to be very stable and unreactive, while atoms with incomplete outer shells (like metals) tend to be highly reactive and may readily form chemical bonds with other atoms in order to complete their outer shell.

  1. Electron configuration tells us how many electrons an atom has and how they are arranged.
  2. The electron configuration of an atom is determined by three quantum numbers that describe the energy and position of each electron within the atom.
  3. Understanding electron configuration is essential to understanding the chemical and physical properties of elements.

Therefore, by studying electron configurations of various elements, scientists can gain valuable insights into the behavior of matter and the properties of different materials.

How To Predict The Lanthanum Electron Configuration

Predicting the electron configuration of lanthanum involves the application of some basic principles. The sequence of filling the atomic orbitals of an element is determined by Aufbau’s principle, which states that electrons occupy the lowest energy level first before moving to higher levels. The Pauli exclusion principle states that no two electrons can have the same four quantum numbers, which are the principal quantum number, orbital angular momentum quantum number, magnetic quantum number, and electron spin quantum number. Another principle to consider is Hund’s rule, which states that electrons fill degenerate orbitals singly before pairing up. From these principles, we can easily predict the electron configuration of lanthanum and other elements by filling up their orbitals in increasing order of energy levels.

Anomalous Electron Configuration Of Lanthanum

Lanthanum is a chemical element with the atomic number 57 and belongs to the series of lanthanides in the periodic table. Its electron configuration is represented as [Xe]5d1 6s2, indicating that one electron occupies the d orbital and the remaining two occupy the s orbital. However, this configuration makes it an exception among the lanthanides, as the other members of this series have a stable f-shell that is half-filled or completely filled. Therefore, Lanthanum exhibits anomalous electron configuration, and here we will discuss its causes.

Causes Of Anomalous Electron Configuration Of Lanthanum

Shielding Effect:

The shielding effect of electrons is a phenomenon in which the inner electrons shield the outer electrons from the full force of the positively charged nucleus. Due to this effect, the effective nuclear charge decreases, and the energy required to remove an electron reduces. In the case of Lanthanum, the 4f electrons experience a very weak effective nuclear charge, leading to poor shielding, and making it difficult to remove an electron from the d orbital.

Energy Differences:

The energy difference between the 5d and 4f orbitals is very small, making it possible for the electrons to occupy both the orbitals. However, due to the bad screening of the 4f electrons, the energy required to remove an electron from the d orbital is quite high, and hence the s orbital is prioritized. As a result, Lanthanum shows an anomalous electron configuration.

Relativistic Effects:

Due to their high speed, electrons experience relativistic effects, where the mass of the electrons increases with the increase in velocity. In the case of Lanthanum, the 5d electrons move at a high speed, leading to an increase in mass, and thus their energy levels shift upwards. Consequently, it becomes more difficult to remove an electron from the d orbital, making the s orbital the preferred choice.
