Hello, today I will be telling you about 3 elements. The elements I will be telling you about are Platinum, Bromine and Xenon. If you want to see where I got the information I will show you at the end of the report.
The first I am going to show you is Platinum. The atomic number of platinum is 78. The atomic weight is 195.078 AMU. It is in group number 10. The melting point is 3221.6o F and the boiling point is 6920.6o f. The number of proton/electrons 78 and the number of neutrons is 117. Platinum was discovered by Julius Caesar Scaliner in 1557. The name came from the Spanish word platina which means silver. Platinum is a very rare, very heavy and soft metal that is silvery white. It can resist oxygen, water, corrosion and acid attacks. It is used in jewelry, to produce strong magnets and to make standard weights. That is some information about Platinum.
The second element I am going to show you is Bromine. The atomic number is 35. The group number is 17. The atomic weight is 79.904 AMU. The melting point is 19.04o f and the boiling point is 137.804o f. The number of protons/electrons is 35 and the number of neutrons is 45. Bromine was discovered in 1826 by Antoine-Jerome Balard. The name came from the Greek word bromos meaning stench. It’s a reddish brown liquid with irritating fumes that give off poisonous vapor. It can cause severe burns. It occurs in compounds in sea water. It is used in dyes, disinfectants and photographic chemicals. That is some information about Bromine.
This is the last element that I am going to show you. The atomic number is 54. The group number is 18. The atomic weight is 131.29 AMU. The boiling point is -162.58o f and the melting point is -169.42o f. The number of protons/electrons it has is 54 and the number of neutrons is 77. Xenon was discovered by Sir William Ramsay and Marils William Travers in 1898. The name Xenon comes from the Greek word Xenos meaning stranger. It is a heavy, colorless and odorless noble gas that reacts with fluorine. It is obtained in small quantities in liquid air. An electrical excitation of Xenon produces a burst of brilliant white light. It’s used for filling flash lights and other powerful lamps, used in bubble chambers and modern nuclear power reactors. That is my final element that I will show you.
I will show you the websites that I used to get this wonderful information.
Those are the websites that I used.
Well, I showed you all three elements that I picked. I hope you learned a lot about Platinum, Bromine and Xenon. Thanks for reading!
