The metals and non-metals have been arranged according to their densities in the Periodic Table.
Yes and No, your question is to general to provide a specific answer.
Metals: Shiny 'metallic' appearance Solids at room temperature (except mercury) High melting points High densities Large atomic radii Non Metals: High ionization energies High electronegativities Poor thermal conductors Poor electrical conductors Brittle solids Little or no metallic luster Gain electrons easily Metalloids: Electronegativities between those of metals and nonmetals Ionization energies between those of metals and nonmetals Possess some characteristics of metals/some of nonmetals Reactivity depends on properties of other elements in reaction Often make good semiconductors
Wikianswers will not do your homework for, but it can offer advice. The conclusion will depend on what you discuss in your project, but in general it should summarize the basic ideas drawn from the project.
The fundamental difference between metals and nonmetals is that metals tend to lose electrons in chemical reactions, and nonmetals tend to gain electrons in chemical reactions (not including the noble gases which are also a type of nonmetal and which are not reactive). In terms of physical properties, metals have a distinctive metallic appearance, shiny and silvery; they are good electrical conductors, they are flexible (although it is possible to formulate less flexible alloys) and usually solid, except for mercury which is liquid. Nonmetals come in other colors, are generally not good electrical conductors, and come in a variety of phases, solid, liquid, or gas.
Metals have 1, 2, or 3 outer energy level electrons. (except lead and zinc which have 4) nonmetals have 4 or more outer electrons in general.
In strict logical inference, nothing, because there could be very dense nonmetals to compensate for the gases. However, in fact the densities of nonmetals on average are less than the densities of metals.
Nonmetals are generally the opposite of metals. They are very brittle, are not good conductors of heat and electricity, and are dull. Most nonmetals are gases at room temperature, which means they have low boiling points. They have lower densities than nonmetals.
a general conclusion is like an overall outcome. for example: the class' general conclusion was that there should be no homework for a week.

No. Both oxygen and bronie are nonmetals. As a general rule, nonmetals will form covalent bonds with one another.
Increase from left to middle and decrease from there to the right.
All materials have advantages or disadvantages - this depends on their use and cannot be enumerated in general.
