Strontium Research Paper
Strontium- is named after Strontian a small town in Scotland
Atomic number- 38
Symbol- Sr
Mass- 87.62
Density- 2.63 g/cm3
Melting point- 7770C
Boiling point- 13820C
State at room temp- In room temperature strontium is an alkaline earth metal. Alkaline earth metals are silvery, shiny and relatively soft metals, they are fairly reactive and they all occur in nature, but are only found in Compounds and minerals, not in their elemental forms.
Solid strength- in a room temperature environment strontium has the strength of 4.99.
Colour- Freshly cut strontium has a silvery colour but after a formation with Oxide it rabidly turns a yellowish colour. When strontium is finely divided its volatile salts can lend a beautiful crimson colour to flames. …show more content…
In 1790 he was studying the mineral witherite (BaC03) and when he mixed it in with hydrochloric acid (HC1) he was surprised at the result he got. Shocked at the result he assumed that an unknown mineral has contaminated his sample of witherite. He named the unknown mineral strontianite (SrCO3). Later in 1798 it was separated into its pure form by Scottish physician and chemist, Thomas Chares Hope. Strontium was first isolated by English Chemist Sir Humphry Davy in 1808.
How and where is the element found?-
Strontium commonly occurs in nature and forms up to 0.034 of igneous rocks and is also found I the form of the Sulphate mineral Celestine (SrSO4) and Carbonate Strontianite (SrCO3). The main mining areas for Strontium is in areas of UK, Mexico, Turkey and Spain and the world production of strontium ores is approximately 127006 kg every year. Strontium can also be found in sea life living like some coral and even shells. The top three producers of strontium in the world is China, Spain and Mexico and China is the top reserve holder for the …show more content…
There is no substitute for Strontium that gives the brilliant crimson colour for fireworks and flares.
Strontium does need other elements to be useful when to make red fireworks. The elements needed to make it is Strontium salts, Lithium salts, Lithium carbonate, Li2CO3 .To make bright red fireworks you need to include strontium carbonate SrCO3 , it is also found in purple fireworks. Commonly used to make flares as well as Strontium is Phosphorus (P, 15) which allows things to glow in the dark and to catch fire when exposed to air.
The supply risk is fairly high but the main risk for strontium is that it is a health risk. The relative supply risk is 8.6 (1 is very low risk 10 is very high risk) the crustal abundance (the number of atoms of the element per 1 million on the earth’s crust) is 320, the Production concentration (%) is 83 and the reverse distribution (%) is
