25
Which will be the first element to filled in the g sub shell?
121st element
26
Why half and full filled orbital have most stability
1. More symmetrical arrangement
2. Greater exchange energy force
27
Paramagnetic
1. More unpaired electrons
2. Attracted by magnetic field
28
Diamagnetic
1. More paired electrons
2. Repelled by magnetic field
