nitride has a -3 charge
A cation has a positive charge and an anion has a negative charge.
An anion is an ion with a negative charge - so SO42- is an anion
The charge on a sulfate anion is -2.
Sodium Nitride, whenever you have a salt the Cation is called its normal name 'Sodium' while a 'Ide' is added to the end of the Anion 'Nitrogen' -> 'Nitride'
nitride has a -3 charge
No, the nitride ion has a 3- charge
A cation has a positive charge and an anion has a negative charge.
A nitrogen anion forms when a nitrogen atom gains three electrons, forming a nitride ion, N3-.
The charge of a nitride ion is -1 http://www.hypoidgear.com/Gear1/attachments/049_Polyatomic%20Ionic%20Compounds.pdf
Phosphate (PO43-) is a polyatomic anion. The way to tell this is to look at the charge - an anion has a negative charge and a cation has a positive charge.
Nitride ions have a charge of -3.
3- so N3-
An anion is an ion with a negative charge - so SO42- is an anion
It is NOT an element, but the Nitride anion. (N^3-).
An anion is an atom with negative electrical charge.
An anion is an atom with a negative charge, not a leaf.
