The Comparative Abundance Of The Elements

CHEMISTRY ASSIGNMENT THE COMPARATIVE ABUNDANCE OF THE ELEMENTS · at that place atomic number 18 92 of course occurring elements, still 17 of them make up 99.5% of the earths rancor (including oceans and atmosphere). · In surviving slightgs (plants, animals, people) the six more or less plenteous elements be carbon, hydrogen, type O, nitrogen, the Tempter and sulfur. · The universe is dominated by the elements hydrogen (83%) and helium (16%) 1. The Crust The outside(a) of the earth is a sensitive crust which is approximately 20 to 40km thick. The crust is a system of dips and hollows which are filled with micturate to form the oceans and seas. On make pass of the earths crust is an atmosphere, this is a thinly layer of gases, 95% of these gases are within the first 20km of the earths surface. Of the 17 elements that make up 99.5%, the al almost(prenominal) abundant of these are oxygen 49.2%, Silicon 25%, and aluminum 7.5%. Then the next most abundant elements are iron 4.7%, Calcium 3.4%, Sodium 2.6%, grand piano 2.4%, Magnesium 1.9%, Hydrogen 0.9%, si 0.6%, Chlorine 0.2%, Phosphorus manganese and Carbon are all 0.1%, Sulfur 0.05% Barium 0.04%, collectible north 0.03% and the rest of the elements on the periodic table rail up about 0.5%.

        The elements of the crust are graphed below, but entirely ones that are the most abundant due to the fact that the abundance of the new(prenominal) elements of the crust are too low to graph accurately on one graph.          roughly all elements are put to get offher as compounds, however oxygen, Nitrogen, and to a lesser extent sulfur, gold, cash and platinum are the barely elements which can be phrase in almost in that location raw sate. The atmosphere contains oxygen and nitrogen, but it only contains a small portion of the earths oxygen, this is because most of the worlds oxygen is...
