using the building up principle Cr would have an electron configuration of [Ar]4s23d4. Experiments show this is incorrect and the electron configuration for Cr is [Ar]4s13d5. It is more stable to move the electron from the 4s orbital to the 3d orbital and...
orbital diagram naturally leads to the writing of an electron configuration. The electron configuration for chromium is: 1s 2 2s 2 2p 6 3s 2 3p 6 4s 2 3d 4 The orbital diagram above is formatted in such a manner as to place the various orbital types at different energy levels. A ...

However, one can write the electronic configuration just by understanding the Aufbau principle. It states that, in the ground state, the electrons occupy the atomic orbitals in their order of increasing energies, which is given by n+l rule. Higher the value of n+l for the orbital, higher ...
That means each element has its unique electron configuration in its ground state. To start an electron orbital drawing, one needs to understand the order in which electrons fill the orbitals. Electron configurations always start from the first atomic number (1) and continue through each respective...

The order is: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d etc. Orbital Diagram The electron configuration of an atom is a shorthand method of writing the location of electrons by sublevel. The sublevel is written followed by a superscript with the number of electrons in the sublevel. If...
The added electrons fill in the order predicted by the Aufbau principle.Example 2 Predicting Electron Configurations of Ions What is the electron configuration and orbital diagram of: (a) Na+ (b) P3– (c) Al2+ (d) Fe2+ (e) Sm3+ Solution First, write out the electron ...
