Homework Answers
explanation:
for paramagnetic nature it must contain unpaired electrons
Sc3+ : Ar configuration it has no unpaired electrons
Mg2+ : it has also no unpaired electrons
Br- also has no unpaired electrons
Se : 4s24p4:
4p4 means : 4px2 4py1 4pz1
in 4p orbitals there are two unpaired electrons are present . so it is paramagnetic
