Hence, the electronic configuration of cobalt is 1s22s22p63s23p64s23d7that has the energy levels and subshells occupied by the electrons according to the Aufbau principle.

How do you find the electron configuration?

To calculate an electron configuration, divide the periodic table into sections to represent the atomic orbitals, the regions where electrons are contained. Groups one and two are the s-block, three through 12 represent the d-block, 13 to 18 are the p-block and the two rows at the bottom are the f-block.

What is the name of the element with 27 electrons?

Cobalt is a chemical element with symbol Co and atomic number 27.

[Ar] 4s2 3d7.

What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1?

So, an antimony atom with charge +2 has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p1.

The Order of Filling Orbitals

The aufbau principle explains how electrons fill low energy orbitals (closer to the nucleus) before they fill higher energy ones. This means that the 4s orbital which will fill first, followed by all the 3d orbitals and then the 4p orbitals.

What is 1s 2s 2p 3s 3p?

In the question 1s 2s 2p 3s 3p represents electron orbital energy levels. The sequence of orbital energy levels is as always-1s

Which element has the electron configuration 2 8 2?

Magnesium is the element with the electronic configuration of 2,8,2 as its atomic number is 12, since the atomic number is the sum of all the electrons present in the electronic configuration.
