What is the difference between metals and metalloids?

Looking at the arrangement of on we find that there are three families or groups that have a metal, a metalloid and a non-metal in the set of elements....

There is a stair-stepped liked between the metals and non-metals starting at boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), polonium (Po) and ends at astatine...

Given: Name three Metalloids are that have properties of both . Some are semiconductors: Si, Ge. They are boron, silicon, arsenic, germanium, antimony, tellurium, polonium, and astatine. There is...

And the hydroxides of metals are usually bases... And a few oxo-acids are $(HO)_2S(=O)_2$, $(HO)_3P=O$, $HOstackrel+N(=O)O^(-)$, and $(O=)_3ClOH$...what are the conventional names of these acids? On the other hand, when...

are semiconductors because they are neither good nor poor conductors. The of metals are not bound to any particular atom. The electrons are free to move throughout the whole...

But of course the most abundant in our universe are (i) hydrogen, and (ii) helium, another non-metal. See for a percentage breakdown.

Metals lose electrons to become positive ions. The elemental metals bond using which uses a sea of electrons to bond unlimited numbers of atoms together. Most are metals. magnesium, iron,...

The differences among metals, non metals and metalloids are not so clear as one could think, though the metallic properties increase going from the top to the bottom of the...

The common classification for are, possess some characteristics of metals and some of non-metals, semi-conductive, and are metallic lustre. There are only seven classified : Boron Silicon Germanium Arsenic...

Apparently none. Malleability is a property of metals, a result of the between atoms of the metal. I suspect it is closely related to ductility, the ability of a substance...
