Respuesta :
Phosphorus has 5 valence electrons
It wants a full octet for its outer shell
8-5 = 3
It wants a full octet for its outer shell
8-5 = 3
The number of electrons required to complete the outer energy level of the phosphorus atom has been 3.
Phosphorous has been Group 15 nonmetal. The atomic number of phosphorus has been 15.
The electronic configuration has been assigned to fill the subshells. The electronic configuration of Phosphorus has been:
2, 8, 5
The third shell of atoms has 8 electrons. In the third shell of phosphorus, the number of electrons is 5.
In order to complete the outer energy level, the number of electrons required are:
8 = 5 + electrons required
Electrons required = 8 - 5
Electrons required = 3
The number of electrons required to complete the outer energy level of the phosphorus atom has been 3.
