What are Isotopes? Find out in this video from the Properties of Matter chapter. 00:00:02,590 -- 00:00:07,319 In a previous video we learnt about Isotopes. Here are a few more examples. 00:00:07,319 -- 00:00:14,319 There are two isotopic forms of Chlorine: Chlorine 35 and Chlorine 37. Remember isotopes 00:00:16,910 -- 00:00:21,869 have the SAME number of protons, but a different number of neutrons. So how 00:00:21,869 -- 00:00:27,090 many neutrons are in each of these isotopic forms of Chlorine? 00:00:27,090 -- 00:00:30,980 Remember: Mass Number = Number of Protons + Number of 00:00:30,980 -- 00:00:34,030 Neutrons. And the number of protons for each isotope forms 00:00:34,030 -- 00:00:39,960 of elements is the same, so we can rearrange this formula to calculate the number of neutrons 00:00:39,960 -- 00:00:44,969 in each form. Neutrons = Mass Number - Protons 00:00:44,969 -- 00:00:51,969 When we look at Chlorine on the periodic table it has an atomic number of 17, therefore it 00:00:55,149 -- 00:00:59,860 has 17 protons. So Chlorine-35 has a mass of 35. 00:00:59,860 -- 00:01:04,480 Neutrons = Mass Number - Protons = 35 -17 00:01:04,480 -- 00:01:06,909 = 18 18 neutrons 00:01:06,909 -- 00:01:13,909 So Chlorine-37 has a mass of 37. Neutrons = Mass Number - Protons 00:01:15,360 -- 00:01:18,929 = 37 -17 = 20 00:01:18,929 -- 00:01:24,590 20 neutrons. So Chlorine-35 has 18 neutrons and Chlorine 00:01:24,590 -- 00:01:25,999 37 has 20 neutrons. 00:01:25,999 -- 00:01:32,999 Another example of an isotope is Lithium. Lithium has two stable isotopic forms. 00:01:33,340 -- 00:01:38,619 The atomic number of Lithium is 3, therefore it has 3 protons. 00:01:38,619 -- 00:01:43,450 The isotopes of Lithium have 3 neutrons and 4 neutrons respectively. 00:01:43,450 -- 00:01:48,729 How do we calculate each of the isotopes mass number? 00:01:48,729 -- 00:01:52,349 Remember, Mass Number = Number of Protons + Number of 00:01:52,349 -- 00:01:56,209 Neutrons. So for one isotopic form the mass number would 00:01:56,209 -- 00:02:00,059 be: 3 + 3 = 6 00:02:00,059 -- 00:02:04,489 So we would have Li-6 And for the other form, the mass number would 00:02:04,489 -- 00:02:05,599 be 3+4 = 7 00:02:05,599 -- 00:02:09,580 So we would have Li- 7 Want to learn more?

• The Periodic Table: Crash Course Chemistry #4
Hank gives us a tour of the most important table ever, including the life story of the obsessive man who championed it, Dmitri Mendeleev. The periodic table of elements is a concise, information-dense catalog of all of the different sorts of atoms in the universe, and it has a wealth of information to tell us if we can learn to read it.

Box 93, Toronto P Toronto, ON, M5S2S6 ------------------------------------------ Written, Directed, Produced, Edited and Sung by Mitchell Moffit. Based on the "Can-Can" music, by Offenbach. LYRICS: There's Hydrogen and Helium Then Lithium, Beryllium Boron, Carbon everywhere Nitrogen all through the air With Oxygen so you can breathe And Fluorine for your pretty teeth Neon to light up the signs Sodium for salty times Magnesium, Aluminium, Silicon Phosphorus, then Sulfur, Chlorine and Argon Potassium, and Calcium so you'll grow strong Scandium, Titanium, Vanadium and Chromium and Manganese CHORUS This is the Periodic Table Noble gas is stable Halogens and Alkali react agressively Each period will see new outer shells While electrons are added moving to the right Iron is the 26th Then Cobalt, Nickel coins you get Copper, Zinc and Gallium Germanium and Arsenic Selenium and Bromine film While Krypton helps light up your room Rubidium and Strontium then Yttrium, Zirconium Niobium, Molybdenum, Technetium Ruthenium, Rhodium, Palladium Silver-ware then Cadmium and Indium Tin-cans, Antimony then Tellurium and Iodine and Xenon and then Caesium and... Barium is 56 and this is where the table splits Where Lanthanides have just begun Lanthanum, Cerium and Praseodymium Neodymium's next too Promethium, then 62's Samarium, Europium, Gadolinium and Terbium Dysprosium, Holmium, Erbium, Thulium Ytterbium, Lutetium Hafnium, Tantalum, Tungsten then we're on to Rhenium, Osmium and Iridium Platinum, Gold to make you rich till you grow old Mercury to tell you when it's really cold Thallium and Lead then Bismuth for your tummy Polonium, Astatine would not be yummy Radon, Francium will last a little time Radium then Actinides at 89 REPEAT CHORUS Actinium, Thorium, Protactinium Uranium, Neptunium, Plutonium Americium, Curium, Berkelium Californium, Einsteinium, Fermium Mendelevium, Nobelium, Lawrencium Rutherfordium, Dubnium, Seaborgium Bohrium, Hassium then Meitnerium Darmstadtium, Roentgenium, Copernicium Ununtrium, Flerovium Ununpentium, Livermorium Ununseptium, Ununoctium And then we're done!!
