All metals tend to conduct electricity. For the cheapest but hardest I would suggest high speed steel (HSS). It's not the hardest or the cheapest but is a good compromise.
Elements tend to undergo chemical reactions that increase stability.
Electrons. One of the definitions of a "metal" is that electrons can move somewhat freely through the material, so that the metal can conduct electricity. Non-metals are generally good insulators, and not much electricity can flow through them.
The 3 characteristics of a nonmetal's is that they don't conduct heat very well, they are very hard and brittle, can be solids liquids and gasses at room temp where as metals are always solid apart from mercury and they don't conduct electricity, there is 1 exception which is carbon which does conduct electricity but is a metal.
The electron configurations of the elements in each main group are regular and consistent:the elements in each group have the same number of valence electrons.
Usually, yes.
Atoms of materials that conduct electricity best tend to be held together by metallic bonds. This is the attraction between positively charged nuclei in metal atoms and the delocalized electrons in the metal.
Nonmetals tend to have lower melting and boiling points than metals. They tend to be dull and brittle. They do not conduct heat or electricity. They are insulators.
All metals tend to conduct electricity. For the cheapest but hardest I would suggest high speed steel (HSS). It's not the hardest or the cheapest but is a good compromise.
Yes! The elements on the right side of the periodic table are called metals and are the best conductors of electricity. The elements on the left are called nonmetals and they conduct heat and electricity the worst.
The Halogens, Fluorine, Chlorine, Bromine, Iodine and Astatine.
its the elements in a vertical column and they tend to have similar properties (related)
On the periodic table, Groups 4 - 7 tend to form negative ions. These groups tend to gain electrons, thus forming negative ions.
They are reactive, but selective with elements that they will bond with. Most bond with oxygen and oxygen bonds with itself. Elements in the same families tend to bond with other elements similarly, but there are no hard and fast rules.
Non-metals tend to not conduct heat
The vertical elements are called groups. They have similar chemical properties.
They are lustrous, ductile, and malleable, as well as good conductors of heat and electricity, and they tend to have high density.
