It gains one or more electrons.

A negative ion is formed when an atom or molecule gains one or more electrons, giving it a net negative charge. This can happen through processes such as electron capture or the transfer of electrons from another atom or molecule.
The negative ion of lithium sulfide is sulfide ion (S2-). This is formed when lithium sulfide (Li2S) dissociates into its ions in solution.
A uni-negative ion is an ion with a single negative charge. This means the ion has gained an extra electron, giving it a net negative charge of -1. Uni-negative ions are commonly seen in chemical reactions and can play important roles in various processes.
The hydration of an ion is negative because energy is released when water molecules surround and stabilize the ion. This release of energy is favorable and results in a negative enthalpy change. The hydration process is exothermic, meaning it releases heat.
Anions are the other name for negative ions. They are formed when atoms gain electrons, giving them a negative charge.
A negative ion is formed by the addition of negatively charged electrons. The protons do not change.
A salt
A negative ion (anion) is formed after gain of electrons in the atom.A positive ion (cation) is formed after loss of electrons from the atom.
Eletron
A positive ion is formed when atoms lose electrons. When a cell gains an electron it becomes negative
-3
A positive ion is formed when atoms lose electrons. When a cell gains an electron it becomes negative
The negative ion of lithium sulfide is sulfide ion (S2-). This is formed when lithium sulfide (Li2S) dissociates into its ions in solution.
Cl- is formed when KCl is dissolved.
A uni-negative ion is an ion with a single negative charge. This means the ion has gained an extra electron, giving it a net negative charge of -1. Uni-negative ions are commonly seen in chemical reactions and can play important roles in various processes.
Br-. Bromine will grab an electron to make itself more stable, which makes it a negative ion.
The hydration of an ion is negative because energy is released when water molecules surround and stabilize the ion. This release of energy is favorable and results in a negative enthalpy change. The hydration process is exothermic, meaning it releases heat.
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.
