Thread: metals and non metals

i've just read about metals and non metals......

Some books say that there are 22 non metals while some says 16 or 18
also the total elements are 112 or 117
and naturally occuring ones 88 or 92

can somebody give me a link as to where i can get the most accurate long form of periodic table.

Please,
Thanks.

The metals of the periodic table are formally defined as lithium, beryllium, sodium, magnesium, aluminum, potassium, calcium, scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, copper, zinc, gallium, rubidium, strontium, yttrium, zirconium, niobium, molybdenum, technetium, ruthenium, rhodium, palladium, silver, cadmium, indium, tin, antimony, caesium, barium, lanthanum, hafnium, tantalum, tungsten, rhenium, osmium, iridium, platinum, gold, mercury, thallium, lead, and bismuth[1].

88 metals and metalloids, 18-20 Non-metals, but more may be discovered...

Nevertheless, even these 20 elements tend to become metallic at large enough pressures.
