A
Increased effective nuclear charge is balanced by decreased screening effect of electrons in (n-1)d-orbitals
B
Increased effective nuclear charge is balanced by increased screening effect of (n-1)d-orbitals
C
Decreased effective nuclear charge is balanced by increased screening effect of electrons in (n-1)d-orbitals
D
None of these
Solution:
From
Cr
to
Cu,
elements have half or more than half filled (n-1)d-orbitals. Here, an increase in effective nuclear charge is balanced by increased screening effect of electrons in (n - 1)d-orbitals.
