How to Find the Ionic Charge for Phosphorous (P)

Описание: Using a simple, general trend for the ionic charge for elements on the Periodic Table, in this video we find the ionic charge for Phosphorous (P). The periodic table is organized like a chart for ionic charge with elements in many groups having the same charge.

Often in chemistry you’ll use the ionic charge of an element like Phosphorous to figure predict the products of a reaction or write the name or formula for a compound.

We can also look at the electron configuration for an element like Phosphorous to determine the number of valence electrons in the highest energy level.

Note that when we look at the charge on ions, it is important to understand that ions come in pairs. In an ionic compound like NaCl, the Na is a positive ion (Na+) and has transferred/lost an electron to the Chlorine atom which now has an extra electron and is negative (Cl-). We can dissolve NaCl in water and it will split apart into Na+ and Cl-. The electron from the Na is now with the Cl.
