Yes, there is a limit to negative charge that can occur on an ion.
This is -1.
It depends on what ion it is. If it is a cation, then the ion has a positive charge and an anion has a negative charge.
A charge which is not a positive charge is a negative charge.
A negative charge is the opposite of an ion. An Ion with a negative charge becomes an Anion. Normally with a negative charge they are called Electrons. See electrons for more help
An ion is an atom with a positive or negative charge.
An atom with a charge (either positive or negative) is called an "ion." An ion with a positive charge is called a "cation" and an ion with a negative charge is called an "anion ."
An electron has a negative charge. Also an ion in which there are more electrons than protons has a negative charge. Such an ion is called as anion.
Fluoride ion is a singly negative ion.
The hydroxide ion, OH-, has a negative charge of 1-.
An ion's charge will be either positive or negative, but not both. The charges are mutually exclusive. A positive ion is called a cation, and a negative ion is called an anion.
If the ion is positive, then the loss of an electron will result in the ion having one greater positive charge. (A +3 ion will be +4.) If the ion is negative, then the loss of an electron will result in the ion being one less negative than it was previously. (A -4 ion wil be -3. A -1 ion will be neutral and have a zero charge.)
