Single Choice
The decreases in atomic volume from Cr to Cu is very negligible because
Aincrease in nuclear change balanced by increase in screening effect
Correct Answer
Bscreening effect of d-electrons.
Cunpaired electrons of Cr
Dnone
Solution
The decreases in atomic volume from Cr to Cu is very negligible because increase in nuclear change balanced by Increase in screening effect. because as we go rightwards in a period due to poor shielding of d-electrons, effective nuclear charge increases and size decreases. But due to screening effect size increase. Hence, size of Cr & Cu is approximately same.
Hence, Option "A" is the correct answer.
