Asprin can be made by adding 200.0 g of salicylinc

Temperature and pressure

Well to my expert knowledge and my exquisite calculations i think the the negative ion # 412 is the key to sucess

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.
