You talk down to and degrade the positive ions until they turn negative.
You have to add an electron to a neutral atom/molecule.
Na is positive ion,Cl is negative ion
when an atom loose electron it become negative ion and when it gains electron it become positive ion
A negative ion is called an anion, while a positive ion is called a cation.
There is a different between a postive and negative ion. Ion's depend on protons and electrons. If there is 4 protons and 5 electrons , it would make it a negative ion because the extra electron would have no other neutron to pair up with to make it a balance atom. If there is 4 protons and 3 electrons , it would make it a postive ion because the extra proton doesn't have any other electron to pair up to , to cancel it out. When there is an even amount of electrons and protons then the atom would be a balance atom. So therefore it would have no charge. So therefore telling the difference form a postive and negative ion depends on the extra proton or neutron.
Some are and some are not. One negative ion, the chloride ion, is generally harmless. Another negative ion, the cyanide ion, is highly toxic.

Negative ion. Cl-
Na is positive ion,Cl is negative ion
A positive ion is an ion with no negative charges.
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
negative ion
ion That statement isn't true. An ion is an atom with an uneven amount of protons and electrons.
Yes, its negative ion is called Bromide = Br-
It will be a negative ion, or in other words, a anion.
A negative ion is called an anion, while a positive ion is called a cation.
Br-. Bromine will grab an electron to make itself more stable, which makes it a negative ion.
