Question

what is ions..... . .........​

Answer 1

Answer:

An ion is an atom or molecule that has a net electrical charge. Since the charge of the electron is equal and opposite to that of the proton, the net charge of an ion is non-zero due to its total number of electrons being unequal to its total number of protons

Answer 2

Answer:

• Compounds contain metals as well as non-metals. These elements include charged species which are known as ions.
• Thus, ion is a particle that has a positive or negative charge.
• Anion- negatively charged
• Cation- positively charged
• There can be a single charged atom in an ion or there may be a group of charged atoms in an ion that have a net charge on the compound.
• When a group of atoms carries a charge in a compound it is called as a polyatomic ion.
