-the metalic character increased from the selenium to the polonium 
-the oxygen is a gas
All this element are weak on water dissolution]]> 2017-04-04 18:10:31 UTC https://padlet.com/anaamandaferrerapenate/548pfjmd4yp0/wish/164700043 anaamandaferrerapenate https://padlet.com/anaamandaferrerapenate/548pfjmd4yp0/wish/164892939 It was discovered. Its discoverers are: Joseph Priestley and Carl Willhelm Scheele.
Is called oxygen from the greek words ''Oxys'' and ''Genes'', which together mean ''acid forming''.
The oxygen is found distributed throughout the Earth.
It's important because the living beings need it to perform vital functions, oxygen is used in: 
-Medicine
-Oven manufacture
-Welds
-etc.
Oxygen's isotopes are: 12O,13O, 14O,15O,160,17O,18O,19O,20O,21O,22O,23O,24O,25O,26O,27O,28O.
Three isotopes are nuclearly stable and forteen are unstable]]> 2017-04-05 14:35:19 UTC https://padlet.com/anaamandaferrerapenate/548pfjmd4yp0/wish/164892939 anaamandaferrerapenate https://padlet.com/anaamandaferrerapenate/548pfjmd4yp0/wish/164997818 It was discovered in Prehistory by the Greeks, but Antoine Lavoisier said that Solfour was an element.
The name of this element is derived from the Latin word ''sulphurium'' and the sanskrit word ''sulvere''.
Solfour is necesary for the synthesis of the proteins of the living beings.
Its isotopes are: 26S,27S,28S,29S,30S,31S,32S,33S,34S,35S,36S,37S,38S,39S,40S,41S,42S,43S,44S,45S,46S,47S,48S,49S

The name is derived from ''selene''.the Greek name for the Moon.
We can find selenium in nuts, legume, some mushrooms, vegetables, fruits and Kalp Seaweed.
The importance of Selenium is that is a essential micronutrient  for our organism,that is,  the human body doesn't  make ,for this reason, is indispensable add it to our diet.
Its isotopes are: 74Se,75Se,77Se,78Se, 79Se,80Se]]> 2017-04-05 20:15:38 UTC https://padlet.com/anaamandaferrerapenate/548pfjmd4yp0/wish/164999608 anaamandaferrerapenate https://padlet.com/anaamandaferrerapenate/548pfjmd4yp0/wish/165001802 It is from the Latin Word ''tellus'' what it means ''Earth''.
Tellurium can be obtained combined with gold in the Calaverita,a metallic mineral not very abundant
It is an additive of the steel
