Hello students and then in this question we have to explain the shielding process using the atom of beryllium.
00:06
Okay, so we know that beryllium has an atomic number of four.
00:11
So it will have a 1s 2 electrons and 2s2 electrons.
00:16
So it will have 4s electrons.
00:19
Okay, so we will be having a nucleus, then a 1s layer and then a 2s layer.
00:26
So this will be my nucleus and i will be having two electrons in the 1.
00:31
Orbital and then i will be having two more electrons in the 2s orbital right so we know that electron shielding refers to the blocking of valence shell electrons by the nucleus due to the presence of inertial electrons so we can say these these electrons will be doing the shielding and these will be these will shield this will shield the effect of the outer electrons okay towards the nucleus.
01:03
So we can say that it turns out that the field s orbital, that is 1s electrons, will slightly shield...
