What are examples of metals, non-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...

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...

A metalloid is an element whose properties are "in between" those of . For example, metals are excellent electothermal conductors, and nonmetals are non-conductors. Metalloids are described as semiconductors....

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

Metals---these are generally hard( Na and K are exceptions),lustrous,malleable,ductile,conducting and electron giving elements. Non metal---reverse of metals.(eg; they're generally soft,non-lustrous etc.) Metalloids--these are the elements which show properties of...

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...

And we would also expect them to increase in the order...... $"metals"$ $<$ $"non-metals"$ $<$ $"Noble Gases"$. So why? Metals are generally regarded as electron-rich materials, whose are delocalized and...

Ionic bonds occur between anions and cations. And cations may be metallic, i.e., $M^(2+)$, or they may be non-metallic, i.e. ammonium salts, $NH_4^+$. And anions, while typically non-metallic, i.e. $X^-$...

........And non-metals typically form an ion isoelectronic with the next Noble Gas. A Group 17 element typically forms an ion with a single negative charge: $1/2X_2 + e^(-) rarr X^-$...
