Mad as a Hatter! It's believed, is that hatters really did go mad. The chemicals used in hat-making included mercurous nitrate, used in curing felt and prolonged exposure to the mercury vapors caused mercury poisoning.]]> 2019-03-14 21:50:31 UTC https://padlet.com/n_f1/science_year7/wish/341552318 Hydrogen n_f1 https://padlet.com/n_f1/science_year7/wish/341552447 2019-03-14 21:51:18 UTC https://padlet.com/n_f1/science_year7/wish/341552447 Oxygen n_f1 https://padlet.com/n_f1/science_year7/wish/341552510 2019-03-14 21:51:35 UTC https://padlet.com/n_f1/science_year7/wish/341552510 Helium n_f1 https://padlet.com/n_f1/science_year7/wish/341552647 2019-03-14 21:52:13 UTC https://padlet.com/n_f1/science_year7/wish/341552647 Lithium n_f1 https://padlet.com/n_f1/science_year7/wish/341552677 2019-03-14 21:52:19 UTC https://padlet.com/n_f1/science_year7/wish/341552677 Beryllium n_f1 https://padlet.com/n_f1/science_year7/wish/341552708 2019-03-14 21:52:26 UTC https://padlet.com/n_f1/science_year7/wish/341552708 Boron n_f1 https://padlet.com/n_f1/science_year7/wish/341553573 2019-03-14 21:57:07 UTC https://padlet.com/n_f1/science_year7/wish/341553573 Carbon n_f1 https://padlet.com/n_f1/science_year7/wish/341553770 2019-03-14 21:58:17 UTC https://padlet.com/n_f1/science_year7/wish/341553770 Nitrogen n_f1 https://padlet.com/n_f1/science_year7/wish/341553788 2019-03-14 21:58:26 UTC https://padlet.com/n_f1/science_year7/wish/341553788 Iodine n_f1 https://padlet.com/n_f1/science_year7/wish/341553986 2019-03-14 21:59:52 UTC https://padlet.com/n_f1/science_year7/wish/341553986 Neon n_f1 https://padlet.com/n_f1/science_year7/wish/341554003 2019-03-14 21:59:57 UTC https://padlet.com/n_f1/science_year7/wish/341554003 Sodium n_f1 https://padlet.com/n_f1/science_year7/wish/341554034 2019-03-14 22:00:08 UTC https://padlet.com/n_f1/science_year7/wish/341554034 Magnesium n_f1 https://padlet.com/n_f1/science_year7/wish/341554050 2019-03-14 22:00:14 UTC https://padlet.com/n_f1/science_year7/wish/341554050 Manganese n_f1 https://padlet.com/n_f1/science_year7/wish/341554107 2019-03-14 22:00:37 UTC https://padlet.com/n_f1/science_year7/wish/341554107 Aluminium n_f1 https://padlet.com/n_f1/science_year7/wish/341554165 2019-03-14 22:00:56 UTC https://padlet.com/n_f1/science_year7/wish/341554165 Silicon n_f1 https://padlet.com/n_f1/science_year7/wish/341554222 2019-03-14 22:01:13 UTC https://padlet.com/n_f1/science_year7/wish/341554222 Phosphorus n_f1 https://padlet.com/n_f1/science_year7/wish/341554271 2019-03-14 22:01:31 UTC https://padlet.com/n_f1/science_year7/wish/341554271 Sulfur n_f1 https://padlet.com/n_f1/science_year7/wish/341554320 2019-03-14 22:01:45 UTC https://padlet.com/n_f1/science_year7/wish/341554320 Chlorine n_f1 https://padlet.com/n_f1/science_year7/wish/341554476 2019-03-14 22:02:29 UTC https://padlet.com/n_f1/science_year7/wish/341554476 Argon n_f1 https://padlet.com/n_f1/science_year7/wish/341554513 2019-03-14 22:02:37 UTC https://padlet.com/n_f1/science_year7/wish/341554513 Potassium n_f1 https://padlet.com/n_f1/science_year7/wish/341554653 2019-03-14 22:03:16 UTC https://padlet.com/n_f1/science_year7/wish/341554653 Calcium- Taken n_f1 https://padlet.com/n_f1/science_year7/wish/341554690
