Frequently Asked Questions on Electronic Configuration

What is electronic configuration?

Electronic configuration is the distribution of electrons within the energy levels, sublevels, and orbitals of an atom or molecule.

What are the noble gases present in first 30 elements?

Noble elements preset in first 30 elements are helium, neon and argon.

What is the Hund’s rule of electronic configuration of the first 30 elements?

When applying Hund’s Rule to electronic configurations of the first 30 elements, we can observe that electrons fill the orbitals in a way that maximizes the number of unpaired electrons, which leads to greater stability.

What is the formulas to calculate maximum number of electrons in shell with principal quantum number n?

The formula to calculate the maximum number of electrons present in shell with principal quantum number n is = 2n² .

How to calculate value of L from principal quantum number n?

For principal quantum number n , the value of L is in between 0 to n-1 .

Are all d-block elements transition elements?

No, all d-block elements are not transition elements, however all transition elements belongs to d-block.

What is the SPDF configuration?

SPDF configuration represents the distribution of electrons in the atomic orbitals of an atom, using the letters S, P, D, and F to denote different types of orbitals:

• S orbitals has one orbital.
• P orbitals has three orbitals.
• D orbitals has five orbitals.
• F orbitals has seven orbitals.

Electronic configuration describes the distribution of electrons in atomic orbits. It tells about how electrons are arranged in the orbits inside the atom. Knowing any element’s electronic configuration helps us to find its physical and chemical properties.

In this article, we will learn how to write electronic configuration of elements, Electronic configuration of the first 30 elements, and the significance of electric configuration.
