Ancient Greece is known to be the birthplace of atom. It was when Democritus, a natural philosopher who proclaimed that matter was composed of indestructible particles called atom. He first described these particles using the Greek word “atomos” which means uncuttable or the smallest indivisible particle of matter, something that cannot be divided. Democritus even extrapolated that matter was composed of these tiny particles that formed the mass of the substances. It was a radical idea at that time but when John Dalton proposed his modern atomic theory of matter in 1803, the idea was revived. Read details at http://www.helium.com/items/1351260
An overview about the chemical element Rubidium
If we take a look at the periodic table of elements, Rubidium is a chemical element with the symbol Rb and atomic weight of 37. Its name was derived from the word “rubidus” which means deepest red. Although it is described as a soft, silvery-white metal, it gives a reddish-violet color to a flame, hence its name. It was recorded to have a melting point of 390C or equivalent to 1020F and a boiling point of 6880C or equivalent to 1,2700F. Read details at http://www.helium.com/items/1352179
An overview about the chemical element Silicon
Known as the most used chemical element in industry, Silicon is the principal component of most semiconductor devices, particularly integrated circuits or microchips. Reviewing the periodic table of elements, Silicon has an atomic number of 14 and uses the symbol Si which was derived from the Latin word silex or silicis which means for flint. It is the most common metalloid with an atomic mass of 28.09. Read details at http://www.helium.com/items/1352333

Strontium is an alkaline earth metal using a chemical symbol Sr, with atomic number of 38, atomic weight of 87.62 and atomic volume of 33.7 cc/mole. It can be described as a soft silver-white but it turns yellow when exposed to air making it a yellowish metallic element that is highly reactive chemically. Known to be a malleable metal, it was observed to have a melting point of 10420K and boiling point of 16570K. READ MORE AT http://www.helium.com/items/1354959
An overview about the chemical element Ruthenium
A chemical element that is considered rare transition metal, very hard and brittle. It is silver gray in color and one of the platinum metals from group eight of the periodic table of element together with rhodium, palladium, osmium, iridium, and platinum. It is used as hardener in alloys of platinum and palladium that even only small amounts of it can increase the hardness of platinum and palladium. The corrosion resistance of titanium is increased markedly by the addition of a small amount of ruthenium. READ MORE AT http://www.helium.com/items/1354952
An overview about the chemical element Selenium
With an atomic number of 34, atomic mass of 78.96 and represented by a chemical symbol Se, Selenium is a chemical element that is considered chemically related to sulfur and tellurium. It is a mineral that is essential to good health but required only small amount for it can be toxic if taken in large quantity. In the periodic table of elements, Selenium belongs to the Chalcogen or group 16. It is classified as non-metallic that stays solid at 2980K. READ MORE AT http://www.helium.com/items/1354947

An overview about the chemical element Silver
One of the well known chemical elements is Silver. It is a white, lustrous transition element that is represented by the chemical symbol Ag which was derived from a Latin word “Argentum” which means silver. The name silver came from an old English or Anglo-Saxon word “seolfor” which also means silver. It has an atomic number of 47, atomic weight of 107.87 and atomic volume of 10.3 cc/mol. Silver is slightly harder than gold. It is also described as ductile and malleable metal with a melting point of 961.930C or 17610F, boiling point of 22.120C, specific gravity of 10.50 (200C) and valences of 1 and 2. In the periodic table of elements, Silver is part of period 5 with elements like Zirconium, Tin and Iodine and belongs to group 11 family with Copper, Gold and Roentgenium.
