Soluble minerals in the ocean· In 60 ml salf water and evaporated 3.5% minerals by weight· Galapagos mineral weight 3.8% because less fresh water· what do you think is the weight difference between an element and its ion?· Much less than microgramsVideo 2· Elements salts (ions)· Ca calsium· Mg magnesium· Na soldium· Have electrons that can be easily removed· Table salt is sodium chloride· Dolomite = calsium carbonate and magnesium carbonate can buy in supplements· Can have mercury and is dangerous· Vertical have similar properties horizontal very different· Salts are charged species· Nucleus are protons that are positively charged, number of protons determine the element· Even number of protons to balance out the charge· If you put elemental sodium into water catches fire, sodium trioxide and produces elemental hydrogen· An element has a balanced number of electrons and protons when it is in a non-ionized or neutral state. Elements can also be anions if there are more electrons than protons or cations if there are more protons than electrons. If you feel you need a refresher on some basic chemistry concepts, review the chemistry primer available here.
