Step 2:: Identify the Element
Phosphorus is a nonmetal element located in Group 15 (VA) of the periodic table. Its atomic number is 15.
Step 3:: Determine Electron Configuration
The electron configuration of phosphorus is $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{3}
Step 4:: Calculate Valence Electrons
Phosphorus has 5 valence electrons in its outer shell (3s and 3p orbitals).
Step 5:: Determine Typical Ionic Charge
In most ionic compounds, phosphorus tends to form a $$3^{-}$$ charge by gaining 3 electrons to complete its octet.
Step 6:: Verify Common Oxidation States
- $$+3$$ and $$+5$$ in various oxide compounds
Phosphorus can have multiple oxidation states, but the most common are:
Final Answer
The most common charge of phosphorus when forming ions is 3^{-}.
