Total number of electrons in Cu atom havijng `m_(1)=0` :

The total number of electrons in Cr atom for which m=0:

If X = Total number of valence electrons in free atom, Y = Total number of nonbonding or lone pairs of electrons and Z = Total number of bonding or shared electrons, then the CORRECT formula to calculate formal charge on an atom is:

In an atom, the total number of electrons having quantum number n = 4, |m_(l)| = 1 and m_(s) = - (1)/(2) is

In an atom, the total number of electrons having quantum numbers n = 4,|m_(l)| = 1 and m_(s) =- (1)/(2) is

In an atom, the total number of electrons .having quantum numbers. n = 4 , |m_(l)|=1 is :

In an atom, the total number of electrons .having quantum numbers. n = 4 , |m_(l)|=1 is :

In an atom, the total number of electrons having quantum numbers n=4, abs(m_l) =1 and m_s=-(1/2) is
