Is silver a metal or non metal?
silver (Ag), chemical element, a white lustrous metal valued for its decorative beauty and electrical conductivity. Silver is located in Group 11 (Ib) and Period 5 of the periodic table, between copper (Period 4) and gold (Period 6), and its physical and chemical properties are intermediate between those two metals.
Is platinum heavy metal?
Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic numbers. The earliest known metals—common metals such as iron, copper, and tin, and precious metals such as silver, gold, and platinum—are heavy metals.
Which is not platinum metal?
With the exception of small alluvial deposits of platinum, palladium, and iridosmine (an alloy of iridium and osmium), virtually no ores exist in which the major metal is from the platinum group.
Is Steel the strongest metal?
While steel is technically an alloy rather than a metal, it is the strongest alloy currently available. Researchers are attempting to create stronger combinations of elements, but for now, steel mixed with a few other elements is considered the strongest.
Is praseodymium a metal or nonmetal?
Praseodymium is a soft malleable, silvery-yellow metal. It is a member of the lanthanide group of the periodic table of elements.
Is element SB a metal or a nonmetal?
Elements sometimes also classified as nonmetals are the metalloids boron (B), silicon (Si), germanium (Ge), arsenic (As), antimony (Sb), tellurium (Te), and astatine (At). The nonmetal selenium (Se) is sometimes instead classified as a metalloid, particularly in environmental chemistry.
Is a helium a metal or nonmetal?
Helium is a noble gas; it does not take part in chemical reactions under ordinary conditions. But non-metals tend to gain electrons to form negative ions. Also, there are many chemical properties that helium does not show as a non-metal. Then how can be helium considered as a non-metal by looking at is chemical properties?
Is a metalloid a metal or a non metal?
The metals which exhibit the highest degree of metallic behaviour is known as metals. Non-metals are such elements which do not possess any metallic behaviour. Metalloids are such elements, which possess some of the properties like metal, while some like non-metal. Metals are placed on the left side of the periodic table.
