What causes shielding effect?
1 Answer
A greater number of electron between the nucleus and the electron in question.
Explanation:
To understand the shielding effect, consider
The value of
To understand this, try think of the atomic orbital theory.
Remember that
where Z is the atomic number and S is the amount of electron between the nucleus and the valence electron.
Example: Why is Cesium a larger element that Potassium?
Cs =
K =
As you can see there are more orbitals separating the valence electrons from the nucleus of the atom, so the nucleus will have less control of the
