Which rule explains the electronic configuration of chromium is [Ar] $$3d^{5} 4s^{1}$$ instead of [Ar]$$3d^{4}4s^{2}$$?
State Hund's rule of maximum multiplicity.
Hund's Rule of Maximum Multiplicity rule states that for a given electron configuration, the term with maximum multiplicity falls lowest in energy. According to this rule electron pairing in p, d and f orbitals cannot occur until each orbital of a given subshell contains one electron each or is singly occupied.
Which rule explains the electronic configuration of chromium is [Ar] $$3d^{5} 4s^{1}$$ instead of [Ar]$$3d^{4}4s^{2}$$?
The largest number of unpaired electrons: $$ F,\ N, \ S^{2-},\ Mg^{2+},\ Sc^{3+}, \ Ti^{3+}$$
If Hund's rule is not followed, magnetic moment if Fe$$^{2+}$$, Mn$$^\oplus$$ and Cr all having 24 electrons will be in order :
According to Hund's rule, the distribution of electron within the various orbitals of a given sub-shell is one which is associated with :
Using the Hund rules, find the basic term of the atom whose partially filled subshell contains (a) three p electrons; (b) four p electrons.
Why Hund's rule is called rule of maximum multiplicity ?
State and explain the 'Hund's rule of maximum multiplicity'.
Which of the following statements is correct?
In which of the following orbital diagrams are both Pauli's exclusion principle and Hund's rule violated?
In a set of degenerate orbitals, the electrons distribute themselves to retain similar spins as far as possible. This statement is attributed to :
