118 Elements and Their Symbols and Atomic Numbers
| Name of the Element | Symbol of the Element | Atomic Number |

| Tellurium | Te | 52 |
Silicon is neither metal nor non-metal; it's a metalloid, an element that falls somewhere between the two. The category of metalloid is something of a gray area, with no firm definition of what fits the bill, but metalloids generally have properties of both metals and non-metals.
Lead has atomic symbol Pb and atomic number 82. It is located towards the bottom of the periodic table, and is the heaviest element of the carbon (C) family. The chemical symbol for lead is an abbreviation from the Latin word plumbum, the same root word as plumbing, plumber and plumb-bob still commonly used today.
Uranium was named after the planet Uranus. Allotropes. U. Uranium. 92.
Tantalum (Ta), Osmium (Os), and Rhodium (Rh) are all transition metals as they are located at the center of the periodic table.

Unfortunately, Osmium forms a nasty compound, Osmium tetroxide , when exposed to air. Osmium Tetroxide is toxic, volatile, water soluble, and really wants to kill you. Don't do it. The density of Osmium is 23 grams per Cubic centimeter.
Mainly most of them are solids. Ta, Os and Rh are all metals with a same platinum group. Tantalum (Ta) with a atomic number 73 is a.
Nonmetals are (usually) poor conductors of heat and electricity, and are not malleable or ductile; many of the elemental
nonmetals are gases at room temperature, while others are liquids and others are solids. The metalloids are intermediate in their properties.

Osmium tetroxide is expensive because osmium is a rare element. Osmium is one of the rarest elements in the Earth's crust. Osmium is obtained as a by-product from nickel and copper processing. The US production of Os is probably only about 75 kg/year.
It is the densest of all the elements and is twice as dense as lead. Osmium has only a few uses. It is used to produce very hard alloys for fountain pen tips, instrument pivots, needles and electrical contacts. It is also used in the chemical industry as a catalyst.
Potassium. The name is derived from the english word potash. The chemical symbol K comes from kalium, the Mediaeval Latin for potash, which may have derived from the arabic word qali, meaning alkali. Potassium is a soft, silvery-white metal, member of the alkali group of the periodic chart.
A millimetre of mercury is a manometric unit of pressure, formerly defined as the extra pressure generated by a column of mercury one millimetre high, and currently defined as exactly 133.322387415 pascals. It is denoted mmHg or mm Hg.
Hg is the most common isotope. Mercury makes a blue to ultraviolet color in a tube when a spark is passed through it. The ultraviolet light can kill germs or light fluorescent lamps.
About one-third of the lead in the United States is recycled. The chemical symbol for lead is Pb, which comes from the Latin word plumbum, meaning "waterworks," referring back to ancient times when the metal was widely used in the construction of water pipes.
As you can see in the pie graph at the left, about 97 percent of your body's mass consists of just four major elements— oxygen, carbon, hydrogen, and nitrogen. The six most common elements in living things are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur.
Today, mercury is used for the manufacture of industrial chemicals and for electrical and electronic applications. It can be found in meteorological equipment like thermometers and barometers. Gaseous mercury is used in mercury-vapor lamps which light highways at night.
Mercury is the only metal that is a liquid at normal temperatures and pressure. Basically, it's because mercury is bad at sharing—electrons, that is. Most metal atoms readily share valence electrons with other atoms. The electrons in a mercury atom are bound more tightly than usual to the nucleus.
