Yttrium electron configuration is the method of describing the electron arrangement in the yttrium atom. The electron configuration is dependent on the principle that electrons occupy different energy levels in atoms.

As such, the yttrium electron configuration is guided by the rules of the Aufbau principle. In this article, we will discuss the steps involved in writing yttrium’s electron configuration, including the role of the Aufbau principle.

Step 1: Shell Number

The shell number is also called the principal quantum number or n. The value of the shell number ranges from 1 to 7, and it represents the energy level in which an electron is located.

For yttrium, the atomic number is 39. Thus, yttrium has 39 electrons that need to be arranged in the different shells.

Step 2: Number of Electrons in Orbital

The second step involves assigning electrons to the different orbitals. The orbitals are subshells within a particular shell.

Each orbital can hold a specific number of electrons, which depends on the angular momentum quantum number called l. The value of l determines the shape of the orbital.

The maximum number of electrons that can occupy a particular orbital is given by the formula 2(2l+1). The various orbitals are denoted by letters s, p, d, and f.

The Aufbau principle is essential in this step since it determines the order in which the orbitals are filled. The Aufbau principle states that electrons fill the lowest energy orbitals first before proceeding to the higher energy orbitals.

For instance, in the case of yttrium, the first electron fills the 1s orbital since it is the lowest energy orbital. The second electron fills the 2s orbital, while the third and fourth electrons fill the 2p orbitals.

Step 3: Final Electron Configuration

The final step involves organizing the electrons in their appropriate energy levels and orbitals. For yttrium, the electron configuration is as follows:

1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 4d1 5s2

This configuration indicates that yttrium has two electrons in the 1s orbital, two in the 2s orbital, and six in the 2p orbital. It has two electrons in the 3s orbital, six electrons in the 3p orbital, ten electrons in the 3d orbital, two electrons in the 4s orbital, six electrons in the 4p orbital, one electron in the 4d orbital, and two electrons in the 5s orbital.

Aufbau Principle in Yttrium Electron Configuration

The electron configuration of yttrium follows the Aufbau principle, which is the fundamental rule that guides the arrangement of electrons in atoms. The Aufbau principle requires that electrons fill lower energy orbitals first before moving to higher energy orbitals.

This principle is based on the principle of energy minimization, which is the tendency of atoms to attain the lowest possible energy state. The Aufbau principle plays a significant role in the electron configuration of yttrium.

For example, when filling the 4d orbital, the Aufbau principle requires that the orbital should first be filled by one electron before a second electron can be added. Additionally, the principle requires that electrons are distributed in such a way that the spin of the electrons in the same orbital is as opposed as possible.

Anticlockwise and Clockwise Electron Distribution

According to the Aufbau principle, electrons in an orbital prefer to have their spins opposed to each other. In practice, this means that electrons in an orbital will spin anticlockwise and clockwise directions.

When a particular orbital has two electrons, one spins clockwise and the other counter clockwise. The anticlockwise and clockwise electron distribution is important in yttrium’s electron configuration because it helps to ensure that the electrons in each orbital are distributed evenly.

This distribution helps to minimize the electrostatic repulsion between the electrons.

Conclusion

In summary, writing the electron configuration of yttrium involves three steps that guide the arrangement of electrons. The Aufbau principle plays an essential role in determining the order of filling orbitals.

Additionally, the electron spin in each orbital is anticlockwise and clockwise balanced to avoid electrostatic repulsion. Understanding yttrium’s electron configuration is crucial in understanding the element’s intrinsic properties and its role in high-tech gadgets.

Number of Electrons in Yttrium

Yttrium has 39 electrons that occupy different energy levels and orbitals. The electrons in yttrium are arranged according to their energy levels and orbitals in the electron configuration notation.

The number of electrons in each energy level and orbital is as follows:

– 1s2 2s2 2p6 3s2 3p6: This represents the electrons in the first three energy levels – n=1, n=2, and n=3. Yttrium has a maximum of 18 electrons in these levels.

– 3d10: This represents the electrons in the 3d sublevel where each orbital can hold a maximum of two electrons. – 4s2 4p6 4d1 5s2: This represents the electrons in the 4th and 5th energy levels where yttrium can have a maximum of 21 electrons.

Electron Arrangement in the Atom

The electron arrangement in yttrium follows the Aufbau principle that requires the electrons to occupy the lowest energy levels and orbitals first. The electrons fill the s, p, d, and f orbitals in ascending order of energy levels.

In yttrium, the electrons are arranged in the following orbitals and subshells: 1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, and 5s. The 4d orbital is incomplete with only one electron, which is why yttrium is classified as a transition metal.

Additionally, the 4d orbital characterizes yttrium’s chemical properties and reactivity.

Ground State and Excited State of Yttrium

The ground state of an atom represents the state of the lowest possible energy of its electrons. It is also the most stable state.

Yttrium’s ground state electron configuration notation is [Kr] 4d1,5s2, which represents the arrangement of electrons in the stable state of the atom. The [Kr] represents the krypton noble gas configuration in the previous shell.

Ground State Term Symbol

The term symbol of an atom is a notation that represents the state of the electrons in the atom. For yttrium, the ground-state term symbol is 2D.

This means that there are two electrons in the D orbital, which is either one of the 4d or 5d orbitals.

Excited State Electron Configuration Notation

The excited state electron configuration notation of yttrium depends on how many electrons have transitioned to higher energy levels. The notation is different from the ground state notation since it indicates a state of motion and not stability.

One example of an excited state electron configuration notation for yttrium is [Kr] 4d0,5s23d1, which means that one electron has transitioned from the 4d orbital to 3d orbital.

Energy Level State

Yttrium, like all elements, has various energy levels where its electrons can be located. These energy levels are the principal quantum levels with n=1 to n=7.

The electron configuration of yttrium indicates the energy levels and orbitals in which its electrons are located. The energy level state of yttrium is influenced by its ground state and excited state electron configuration notations, which are indicative of stable and unstable, energetic states of yttrium.

Conclusion

In summary, yttrium, a rare earth metal, has 39 electrons that occupy different energy levels and orbitals. Its electron arrangement follows the Aufbau principle, which requires electrons to occupy the lowest energy orbitals first.
