Description

The electronic configuration of cations is assigned by removing electrons first in the outermost p orbital, followed by the s orbital and finally the d orbitals (if any more electrons need to be removed). Example: calcium (Z=20), 1s22s22p63s23p64s2; Ca2+: EC is 1s22s22p63s23p6 chlorine (Z=17), EC is 1s22s22p63s23p5 Cl- : 1s22s22p63s23p6. The ns electrons are always lost before the (n-1)d when forming cations for transition metals. For example, Zn: [Ar]4s23d10 Zn+2: [Ar]3d10

The newspaper editorial is often referred to as "the voice of the paper." It is up to the staffs to make sure this description is accurate. Everyone has opinion.

Therefore, when an editorialist speaks or writes, the responsibility weighing on his or her expression is extremely heavy.
