What is Oxygen’s ionic charge?
As every electron has a single negative charge, adding two more electrons gives oxygen ion a charge of 2 .
What is the core charge of Al?
The charge of an aluminum ion is typically 3+. This is because the element’s atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons.
What is the charge of Fe?
For example, iron, or Fe, has possible oxidation states of +2, +3, +4, +5 and +6, but its common oxidation states are +2 and +3.
What type of ion is phosphide ion?
P3− ion
In chemistry, a phosphide is a compound containing the P3− ion or its equivalent. Many different phosphides are known, with widely differing structures. Most commonly encountered on the binary phosphides, i.e. those materials consisting only of phosphorus and a less electronegative element.
What is phosphide on the periodic table?
phosphide, any of a class of chemical compounds in which phosphorus is combined with a metal. The phosphide ion is P3−, and phosphides of almost every metal in the periodic table are known. They exhibit a wide variety of chemical and physical properties.

Why is the charge of oxygen 2?
The element oxygen has six valence electrons. To fill up the valence shell the oxygen atom needs two more electrons. As every electron has a single negative charge, adding two more electrons gives oxygen ion a charge of 2 .
How is the core charge for NE calculated?
Core charge can be calculated by taking the number of protons in the nucleus minus the number of core electrons, also called inner shell electrons, and is always a positive value in neutral atoms.
