One - assuming the atom is not an ion.
an ion
A chloride ion in a water solution is represented as Cl-. In solution, the chloride ion is free to move around and interact with other ions and molecules in the water.
Well im not great at science but i know that a atom which gains or loses an electron will gain a negitive/positive charge and become an ion
Electrons can escape and move outside of an ion's electron cloud. This can happen through processes like ionization, where an electron gains enough energy to break free from its parent atom. Once free, these electrons can move independently in the surrounding environment.
An escaped electron is called a FREE electron, simple as that. It means: not bound or belonging to a particular atom (or ion)
An atom with an electric charge is called an ion. An ion is the result of an imbalance in the number of protons and electrons. If there is more protons than electrons then your atom will have a positive charge. If more electons then it will have a negative charge.
When one metal ion shares electrons with another metal ion, it forms a metallic bond. In a metallic bond, the outer electrons of the metal atoms are delocalized and free to move throughout the structure, creating a strong bond. This sharing of electrons allows metals to conduct heat and electricity well.
Proteins. Unless the material is an ion in which case it'd be an ion channel.
Electrons move
Monatomic Ion, because Mono means One (1)
