Web2 × 4.9/3 = 3.3 µB. 2.67 unpaired electrons gives 2.67 4.67 3.53 µB. 10.8 Co(II) is d 7. In tetrahedral complexes, it is generally high spin and has 3 unpaired electrons; in octahedral complexes, it is also typically high spin and also has 3 unpaired electrons; in square planar complexes, it has 1 unpaired electron. WebMost of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule. Some atoms can be stable with an octet even though their valence shell is the 3n shell, which can hold up to …
