what is platinum in the periodic table?
11354
Platinum (Pt), chemical element, the best known and most widely used of the six platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table. A very heavy, precious, silver-white metal, platinum is soft and ductile and has a high melting point and good resistance to corrosion and chemical attack.

Osmium (from Greek ὀσμή osme, "smell") is a chemical element with the symbol Os and atomic number 76. It is a hard, brittle, bluish-white transition metal in the platinum group that is found as a trace element in alloys, mostly in platinum ores.

The transition metals make up the middle block of the periodic table. Like the other elements that are grouped together (alkali metals, noble gases), these metals have very similar properties. Professor Stahl and his research group work with many of the transition metals.

There are four main groups of elements in the periodic table: main group metals, non-metals, metalloids, and transition metals (See types of elements). There are 4 blocks in the periodic table.

Periodic Table of the Elements. The periodic table (also known as the periodic table of elements) is organized so scientists can quickly discern the properties of individual elements such as their mass, electron number, electron configuration and their unique chemical properties.

Rhodium, together with ruthenium, palladium, osmium, iridium, and platinum form a group of elements referred to as the platinum group metals (PGM). Rhodium metal is lustrous and silvery white. Rhodium has a higher melting point and lower density than platinum. It has a high reflectance and is hard and durable.

Platinum is a naturally occurring white metal. It is rarer than gold, and much heavier and harder. Because of its hardness, platinum can be used in a purer form than gold. ... Platinum jewelelry is consequently more expensive than gold jewellery.

Though both gold and platinum are among least reactive transition element metals, but still if we look at the reactivity series of metals we find that gold is more reactive than platinum.

Metals. In the periodic table, you can see a stair-stepped line starting at Boron (B), atomic number 5, and going all the way down to Polonium (Po), atomic number 84. Except for Germanium (Ge) and Antimony (Sb), all the elements to the left of that line can be classified as metals.

An inner transition metal (ITM) of chemical elements on the periodic table. They are normally shown in two rows below all the other elements. They include elements 57-71, or lanthanides, and 89-103, or actinides. The lanthanides are very similar, and the actinides are all radioactive.
