slater configuration: (1s)2(2s2p)8(3s3p)8(3d)10(4s)2
1 4s e-s 18 3s3p3d e-s 10 2s2p1s e-s
σ4s = (1x0.35)+(18x0.85)+(10x1.0) = 25.65
Zeff 4s = Z - σ4s = 30 - 25.65 = 4.35

The effective nuclear charge on the 4s electron of zinc, according to Slater's rule, would be lower than the actual nuclear charge due to shielding effects from inner electrons. It would be less than +30 (the nuclear charge of zinc) since the 3d electrons partially shield the 4s electron from the full charge of the nucleus.

In going down a group in the periodic table what effect does electron shielding generally have on the effective nuclear charge acting on the outermost electron in an atom?
Electron shielding increases down a group in the periodic table, as more electron shells are added. This reduces the effective nuclear charge experienced by the outermost electron, making it easier for that electron to be removed or participate in chemical reactions.
How is the concept of effective nuclear charge used to simplify the numerous electron- electron repulsions in a many electron atom?
The concept of effective nuclear charge takes into account the shielding effect of inner electrons on the outer electrons. By considering the net positive charge experienced by an electron due to both the nucleus and inner electrons, the effective nuclear charge simplifies the analysis of electron-electron repulsions in a many-electron atom. This simplification helps in predicting the electron distribution and properties of atoms more accurately.
What is the approximate effective nuclear charge for a valence electron in krypton?
The approximate effective nuclear charge for a valence electron in krypton is close to +8. This is because the atomic number of krypton is 36, and the core electrons shield some of the positive charge from the nucleus felt by the valence electrons.
Arrange the atoms icreasing order effective nuclear charge by the electron n3 electron shell K Mg P Rh Tithe explain basis for your order?
The arrangement in increasing order of effective nuclear charge is: K < Mg < P < Rh. This order is based on the increasing nuclear charge as we move from left to right across the periodic table. In this case, potassium (K) has the lowest effective nuclear charge due to its lower atomic number and distance of the electron from the nucleus, while rhodium (Rh) has the highest effective nuclear charge as a result of its higher atomic number and greater nuclear attraction on the outermost electron.
What electron in a - sub shell experiences the greatest effective nuclear charge in a many electron atom?
The electron in the same subshell with the highest principal quantum number will experience the greatest effective nuclear charge in a many-electron atom, as it will be closest to the nucleus. Additionally, electrons in higher energy levels (with higher n values) experience less effective nuclear charge due to shielding effects from inner electrons.

What do mean by effective nuclear charge?
Effective nuclear charge is the net charge of an electron in an atom.Z(eff) = Z - S where:Z - atomic numberS - number of shielding electrons

What will be the effective nuclear charge of 4s electron of Br?
Bromine has five 4p electrons.
Is it the closer an electron is to the nucleus the more energy it has?
Yes, when an effective nuclear charge increases it does pull the electrons closer to the nucleus. An electron is a negatively charged part of an atom.
Why do the valence electrons in nitrogen experience a greater effective nuclear charge than the valence electrons in beryllium?
valence electron in nitrogen
Is electronegativity dependent on the number of neutrons?
It is dependent on the proton number (effective nuclear charge) and the number of electron shells (row number).
What is the effective nuclear charge experienced by calcium's valence electrons?
as you know we must first have the electron configuration to get the valence electrons. the electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2. we now have the electron configuration but we dont have the v.e. the last electron in the calcium atom are in the 4s orbital so that means that since it the only electron in the 4s orbital we will use it as a v.e. so as to get the v.e. we will subtract the shielding electrons from the nuclear charge shortly expressed by the formula below. Zeff=S-Z in this case Z will be the sum of the shielding electrons and s is the nuclear charge. Zeff=20-18 Zeff=2+ so the effective nuclear charge is 2+ or 2. hope you like it.
Why is the first ionisation energy of hydrogen and oxygen the same?
The outer valence electron lies in a 1s orbital in Hydrogen. The effective nuclear charge of hydrogen can be taken as Z = 1. The electron that is being ionised in Oxygen lies in a 2p orbital which has an effective nuclear charge of Z = 8-(3.4 or 4.5 or something). The point is, this nuclear charge at a greater distance from the nucleus means the energies of the electrons are similar and so ionisation energis required are too similar.
