Metals make up over 80% of all the elements inexistence.
Metals are structurally important (cars, re-bars for building, window frames, kettles, fridges etc etc).
Metals are chemically important. A HUGE variety of very important chemicals contain metals including salt, most precious stones (excluding diamonds) and... well LOADS, I don't know where to start the question baffles me because the answer is so big!
Metals are HUGELY important for life. No iron means no haemoglobin which means oxygen isn't moving round your body. No calcium means no bones. That is before we talk about enzymes, co-enzyme complexes and movement of ions across the cellular membrane (the last being the basis for life itself).
Metals are catalysts and speed up chemical reactions.
Metals give fireworks their bright flashes and vivid colours.
Metals give colour.
No life would be possible as we know it without metals... no magnesium, no photosynthesis, no trapping of the sun's energy and therefore no food chain and no life.
Buildings... concrete... calcium again.
No batteries. Electricity is generated in batteries by the difference in reactivity between two metals.
No electricity. Carbon in the form of graphite can conduct electricity but good luck building a dynamo out of graphite and nonmetal magnets (which I believe do contain metals despite the name but I could be wrong) and good luck building wires out of graphite along with intricate circuit boards and other components.
Gold and silver... no jewellery!
And in school there would be no group 1 and 2 metal demo, no hydrogen popping from the acid/metal reactions and no Thermit! But, of course, there would be no one to watch them!
for building contractions,..... building bridges .....
The simplest explanation is that metals have valence electrons to give away, and non metals need extra electrons to complete their valence shell.
Metals which are above Carbon in the reactivity series, eg. Magnesium. These metals need to be extracted by electrolysis.
alkaline metals, alkaline earth metals, lanthanides and actinides and metals in mixed groups
I believe that the answer you are looking for is Transition Metals.
No compounds are metals. All metals are elements, although some metals (e.g. brass) are mixtures of metals.
Metals need to be protected against rust and tarnish because rust and tarnish eat metals.
Two Metals, that are different
Nothing in the World is UNIMPORTANT.We need more non metals than metals....our life is the proof
The simplest explanation is that metals have valence electrons to give away, and non metals need extra electrons to complete their valence shell.
I need the answer
You need different atoms...?
Both the alkali metals and halogens because they only need one electron, or only need to lose 1 electron
Metals which are above Carbon in the reactivity series, eg. Magnesium. These metals need to be extracted by electrolysis.
alkali metals need to loose one electron. alkali earth metals need to loose two
Metals tend to lose electrons to form positive ions because, for metals to gain a full outer shell, they need to lose electrons.
the planet is made of minerals, deposits are scattered aroung the earth but not evenly.
In various places and in various quantities throughout the universe. You need to be more specific.
