and the positive sign shows that there is only one proton. ]]> 2018-03-12 01:33:54 UTC https://padlet.com/william_lambkin/rpejfvv3l51t/wish/240668250 Describe the elements properties: william_lambkin https://padlet.com/william_lambkin/rpejfvv3l51t/wish/240669784 state: gas
colour: colourless gas
density: 0.08988 G/L
melting point: 14K
boiling point: 20.3K]]> 2018-03-12 01:43:27 UTC https://padlet.com/william_lambkin/rpejfvv3l51t/wish/240669784 Explain who discovered ydrogen the date and where it was discovered: william_lambkin https://padlet.com/william_lambkin/rpejfvv3l51t/wish/240670793 In 1671, Robert Boyle discovered and described the reaction between iron filings and dilute acids, which results in the production of hydrogen gas. In 1766, Henry Cavendish was the first to recognise hydrogen gas as a discrete substance, by naming the gas from a metal-acid reaction "inflammable air".]]> 2018-03-12 01:49:53 UTC https://padlet.com/william_lambkin/rpejfvv3l51t/wish/240670793 Explain Hydrogen's reactivity by referring to it atomic structure: william_lambkin https://padlet.com/william_lambkin/rpejfvv3l51t/wish/241785911 Hydrogen is very reactive. It combines with most elements to form hydroxides, and it reduces metallic oxides, a reaction that produces the metal in its elemental state. Almost all metals and nonmetals react with Hydrogen at high temperatures.]]> 2018-03-14 10:34:51 UTC https://padlet.com/william_lambkin/rpejfvv3l51t/wish/241785911 Where Hydrogen is produced or found: william_lambkin https://padlet.com/william_lambkin/rpejfvv3l51t/wish/241787115 Hydrogen is the most abundant chemical element in the universe, found in the Sun, other stars and the gas planets in our solar system.]]> 2018-03-14 10:38:48 UTC https://padlet.com/william_lambkin/rpejfvv3l51t/wish/241787115 The impact of Hydrogen's use on the environment: william_lambkin https://padlet.com/william_lambkin/rpejfvv3l51t/wish/241789068 Hydrogen occurs naturally in the atmosphere Its effect on plants or animals: Any effect on animals would be related to oxygen deficient environments. No adverse effect is anticipated to occur to plant life, except for frost produced in the presence of rapidly expanding gases.]]> 2018-03-14 10:45:13 UTC https://padlet.com/william_lambkin/rpejfvv3l51t/wish/241789068 reference list william_lambkin https://padlet.com/william_lambkin/rpejfvv3l51t/wish/242246079 https://www.britannica.com/science/hydrogen
