[1s 2 2s 2 2p 6 3s 2 3p 6] 4s 1 Arrange the following elements in order of INCREASING ionization energies (IE) based on periodic trends, starting with the element that has the lowest IE. Elements: Ca K Rb Br Rb, K, Ca, Br Answer: (d) 3s, 3p and 3d orbitals all have the same energy Explanation: A hydrogen atom has 1st configuration and these its, 3p and 3d orbitals will have same energy wrt 1s orbital. Hence, the element with the electronic configuration [He]2s 1 is lithium (Li).

The trend in electronegativity is shown pictorially below: Example 7: Order the elements Mn, Cs and O in order of increasing electronegativity: Since F is the element with the highest electronegativity, O should be the most electronegative element in this group since it is closest to F. Cs should be the least electronegative since it is the farthest from F. Answer: Cs < Mn < O Second, ionization energy (IE) is the …

The difference is that in the case of sulfur, the electron being removed is one of the 3p x 2 pair. The repulsion between the two electrons in the same orbital creates a higher-energy environment, making the electron easier to remove than predicted.

Potassium (K) atom has 19 electrons. The full electron configuration of Potassium (K) is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1. The abbreviated form - [Ar]4s 1 - means the electron configuration of Argon (Ar), plus one electron in the 4s orbital. Argon has 18 electrons. The one additional electron configuration completes the picture for 19 electrons of
