Cations are ions with a positive charge. Metal cations are formed when metal loses electrons.
Metal atoms become ions when they lose electrons.
Carbon.
The metal, which becomes a cation. The non-metal gains one or more electrons to form an anion.
which material does not loses its shine. Is gold
You can clean a tarnished metal frame of an old vintage purse with baking soda and water. Make a paste out of the baking soda and water and using an old toothbrush, scrub the metal frame of the purse gently. Wipe away the residue with a clean, damp cloth.
Cations are ions with a positive charge. Metal cations are formed when metal loses electrons.
An ionic bond is formed between a metal and a non metal. The METAL loses an electron (or electrons) and it becomes positively charged.
Metal atoms become ions when they lose electrons.
When it gain electrons, it loses ions. (non-metal) Where as when it loses electron, it gains ions. (metal)
Corrosion/rust.
Carbon.
It loses thermodynamic energy.
Because of its high reactivity is not found naturally in its elemental state; Sodium metal tarnished readily in air due to the formation of a layer of Sodium Oxide on the surface of the metal.
I have three items of tarnished silver jewellery
It becomes a cation - loses electrons
