can you list at least 7 differences between metals and nonmetals?
443053
Metals are shiny and are good conductors of heat and electric current. They are malleable and ductile.\nNon-metals are dull, and are poor conductors of heat and electric current. They're brittle and unmalleable.

Many of our metals are solid and homogeneous.  Homogeneous does not mean pure (only one thing) -- it only means that the composition is the same throughout the object.\n\nSo gold yes, or silver.  Also many wooden objects, glass, some food items like the center of bread...  The list goes on forever once you start thinking.

Each group in the periodic table has a characteristic valency (or set of valencies).  This is what you learn.  Look through your text for the valencies of atoms in compounds to give you a feeling for the elements that can have several valencies (like the transition metals).

Any two elements from different sides of the periodic table. More specifically, one from the metal category and one from the nonmetal category.\n\nEDIT: brwneyes, sodium chloride is one example of an ionic bond, not the only kind of ionic bond.

Some metallic and some non-metallic.\nLike Silicium... it it shiny, just like metals, but doesn't conduct electricity, just like non-metals.\nOr Carbon... it is not shiny and doesn't react with acids, like non-metals, but conduct electricity, like metals.

In chemistry, a metal (Greek: Metallon) is an element that readily forms ions (cations) and has metallic bonds. Metals are sometimes described as a lattice of positive ions (cations) surrounded by a cloud of delocalized electrons. The metals are one of the three groups of elements as distinguished by their ionisation and bonding properties, along with the metalloids and nonmetals. On the periodic table, a diagonal line drawn from boron (B) to polonium (Po) separates the metals from the nonmetals. Elements on this line are metalloids, sometimes called semi-metals; elements to the lower left are metals; elements to the upper right are nonmetals.

Metals generally form positive ions. Nonmetals generally form negative ions. The major exception is Hydrogen, a nonmetal that predominantly forms positive ions.

Yes, they do. The simplest example I can do is Fe (iron): it's a transition metal and has 3 oxidation states: 0 (Fe as a metal), +2 (FeO), and +\n3 (Fe2O3).

If you're still looking for an answer, the actual number is 10, not five or six.\n\nThe periodic table can help you see this - that chunck of elements in the middle where all the transition metals are is called the 'd block' and there are 10 elements going across that section.

You need to look at a Periodic Table. The farther to the left of the table an element is, the more metallic it is.

Guess a group 3 metal such as boron or Aluminium

Atomic wt of Al is 13,Cu is 29,Zn is 30 and Fe is 26.So less atomic wt,Al contains more number of atoms in 50gm
