A positive ion is an ion with no negative charges.
Nitric Acid Ion
Cl-
F-
I-
an ionic compound
If in a neutral atom excess electrons one or two or more get attached, then it becomes a negative ion. For example in case of chlorine as it takes one electron from Sodium it becomes a negative ion.
Fluorine is negative and will produce a negative ion.
A compound/molecule with an ionic bond.
negative ion
When an element forms a negative ion, the name changes to IDE, fir example: chloride
N and P for example. Nitrogen will form a N3- the nitride ion.
For example the ion phosphate - (PO4)3-.
an ionic compound
Negative ion. Cl-
Na is positive ion,Cl is negative ion
If in a neutral atom excess electrons one or two or more get attached, then it becomes a negative ion. For example in case of chlorine as it takes one electron from Sodium it becomes a negative ion.
Fluorine is negative and will produce a negative ion.
when an atom loose electron it become negative ion and when it gains electron it become positive ion
A compound/molecule with an ionic bond.
A polyatomic ion is held together by covalent bonds between atoms. They can be either positive or negative. For example, the ammonium ion, NH4+, has a positive charge, and the sulfate ion, SO42-, has a negative charge.
