How many unpaired electrons does Cr3+ have?
3 unpaired electrons
Hence, there are 3 unpaired electrons in Cr3+.
Which is more stable Fe3+ or Cr3+?
Fe3+/ Fe2+ couple has a positive Eo value but small. Thus the stability of Fe3+ is more than Mn3+ but less stable than Cr3+.
What is the hybridization of HF?
The HF molecule ion hybridization is four. The fluorine and hydrogen atoms have s and p orbitals. The sp3 hybridization of the HF molecule is formed when one s orbital and three p orbitals join together to form the HF molecular orbital.
Is HF paramagnetic or diamagnetic?
diamagnetic
The HF involves one electron of H and an unpaired electron from a 2p orbital of F. As per the molecular orbital diagram, there is no unpaired electron in the hybridised orbital, hence it is diamagnetic.
What is the electron configuration of chromium ion Cr3+?
