Phosphorus
Neither of the two answers you have are correct. Phosphorous has five valence electrons, while silicon has four.
Solid silicon exists in a network of silicon atoms just like the tetrahedral arrangement of carbon atoms in diamond, which has the highest melting point. Since the structure is very strong and the Si-Si bond energies [...]

The process is called “Doping”. Si is a semiconductor and adding P brings more free carriers to the semiconductor that helps in conduction.
Crudely, one can say that “P” has valency 5 and Si has valency 4, now when doping is done Si is displaced in crystal lattice by P. The surrounding Si atoms fulfill 4 [...]
1. the effective nuclear charge of silicon is
less than that of phosphorus.
2. False; phosphorus has a lower ionization
energy than silicon.
3. the effective nuclear charge of phosphorus
is less than that of silicon.
4. the outer orbitals of phosphorus are lo-
cated closer to the nucleus than the outer
orbitals of silicon.
5. the outer orbitals of phosphorus are lo-
cated farther [...]

How are the impurities carbon, sulfur, phosphorus and silicon removed from pig iron?
PS: Even if you know how to remove one of them I would really appreciate your anwser. Thanks
The weight of the silicon varied directly as the weight of the phosphorus. When the silicon weighed 400 kilograms, the phosphorus weighed 100 kilograms. What was the weight of the silicon when the phosphorus weighed only 12 kilograms?
