Why do metals often lose their shine and appear dull?
Most metals lose their luster when they are exposed to water because they react with the oxygen in the water and oxidize. An example is iron that reacts with the water to produce iron oxide, or rust.
Why does gold not lose its shine but other metals do?
It does not rust or tarnish because gold will not chemically combine with any substances in the air
What metal never rusts or lose its shine or tarnish?
which material does not loses its shine. Is gold
Do metals prefer to receive electrons in chemical reactions?
Yes. Metals lose their valence electrons to form cations, or positive ions. Once they lose electrons, the number of protons in their nuclei outnumber the electrons, hence the positive charge.
Do alkali metals tend to gain or lose electrons?
Alkali metals tend to lose electrons in chemical reactions.

Does gold tarnish?
No, gold does not tarnish. It is because acids and other gases have no effect on it. It does not lose its shine. It is a least reactive metal.

It does not rust or tarnish because gold will not chemically combine with any substances in the air
Why do coins tarnish?
Tarnish means to lose the shine or lustre due to exposure to air or moisture resulting in oxidisation and discolouration. The term is often applied to coins to describe the general appearance and condition of the coin.
What do very reactive metals lose?
Reactive metals lose electrons when being oxidised.
What metal never rusts or lose its shine or tarnish?
which material does not loses its shine. Is gold
When metals lose electrons what do they form?
Metals lose electrons and form cations to get a full octet.
Why do metals tend to lose electrons to form positive?
Metals tend to lose electrons to form positive ions because, for metals to gain a full outer shell, they need to lose electrons.
Do metals prefer to receive electrons in chemical reactions?
Yes. Metals lose their valence electrons to form cations, or positive ions. Once they lose electrons, the number of protons in their nuclei outnumber the electrons, hence the positive charge.
Will a Pokemon turn shiny at level 100?
If a Pokemon you own is not shiny then no matter what it cannot turn shiny and if you have a shiny Pokemon it will never lose it's shininess
What do valence electrons in metals do?
Metals lose electrons in a chemical reaction.
Do atoms of metallic elements tend to gain or lose electrons?
Metals usually lose electrons, this is why many charges are positive.
