An anion.
The negative ion is the hydroxyl group (OH)-.
This is an anion (negative ion).
Na is positive ion,Cl is negative ion
A negative ion is called an anion, while a positive ion is called a cation.
when an atom loose electron it become negative ion and when it gains electron it become positive ion
The negative ion is the hydroxyl group (OH)-.
This is an anion (negative ion).
Negative.
It has a negative charge of -2.
When the positive ion of a base combines with the negative ion of an acid, they form a salt compound. The positive ion from the base combines with the negative ion from the acid through an ionic bond to create a neutral compound known as a salt.
every element
Na is positive ion,Cl is negative ion
A positive ion is formed when atoms lose electrons. When a cell gains an electron it becomes negative
Cation = negative ion
An electron has a negative charge, so if a neutral atom gains an electron, it becomes a negative ion. A negative ion is called an anion.
A positive ion is an ion with no negative charges.
Ionic bonds form between positive and negative ions.
