Alloys are harder, the different sized atoms make it harder for the atoms to slide past each other when the metal is under stress or when being manipulated therefore making it much more rigid. For example steel is comprised of carbon and iron. In pure iron all the atoms are the same size which allows the them to slide past each other considerably more easily than in steel which is comprised of at least 2 different elements with different sized atoms.
Mixing metals to form alloys allows us to 'fine tune' their properties. The alloy can have properties which are better than any of their constituents. Many alloys are harder than pure metals. An alloy of tin and lead melts more easily than either metal, and was used as solder. The commonest alloys are the steels, which consist of iron with a controlled amount of carbon, and possibly some of many other metals too. Depending on the ingredients, steels can be harder or softer, have different melting points and different resistances to corrosion.
No. There are much more metallic elements than non metallic elements. All of Group 1, 2 and 5 are metals. All of the transition metals (inc. Lanthanides and Actinides) are metals. Also, most elements in group 6 and 7 are metals.
The transition elements are metals. As with all metals, the transition elements are both ductile and malleable, and conduct electricity and heat.
metals
For "only metals" the answer is alloys or intermetallic compounds, formed of course from atom of metals - the bonds are of metallic type.All other chemical compounds contain atoms of chemical elements, metals or nonmetals.
Metals forms several compounds under various conditions. They will form metallic salts. They will also form alloys when combined with other metals.
Alloys are made from a mixture of metals that are usually melted together. In this way brass, pewter, bronze are made. An amalgam which is also an alloy, is easier to make because mercury is a liquid at room temperature and metals dissolve in it.
No metals form molecules; they only exist as ionic compounds or metallic elements or alloys.
A metallic bond exist in metals and alloys.
The metals outnumber the non-metals by a good margin.
NoAlloys are mixtures of metallic elements or metals with other elements (steel is an alloy that can be a mixture of iron and carbon).Rocks are minerals, these are components of the earth and need not contain any metallic elements at all.
Alloys contain metals but also nonmetals.
All pure metals are chemical elements; alloys are not elements.
Mixing metals we can obtain alloys or inter-metallic compounds.
alloys
All metals except alloys of metals are elements, but not all elements are metals.
"Metallic" is not a metal. But elements that are metals, are metallic.
Group 1 or alkali metals are the most metallic elements.
