Respuesta :
In the transition series, the effective nuclear charge rises from left to right over time, much like the p block, which causes an atomic size decrease. Since the d orbital has less effective shielding than the p orbital in this instance, electrons are being added to it.
How does electron shield work?
When there are inner-shell electrons present, the nucleus blocks the valence shell electron attraction. This is known as electron shielding. Due to the spherical nature of the s orbital and its ability to shelter p electrons at the same energy level.
What does the word "orbital" mean?
An atomic orbital is a function used in atomic theory and quantum mechanics to describe the position and wave-like behavior of an electron in an atom.
