The name of the genetic material found in every cell in your body is called DNA. This DNA is responsible for giving you your physical traits for example.
The "valence" electrons are responsible for chemical reactions and bonding. Valence electrons are found in the outer most orbital of the atom, farthest away from the nucleus.

oxygen and silicon are the two elements that make up more than 80 percent of the atoms found in the Earths crust...(there is a constructed response for you guys)
Cabon - C Hydrogen- H Oxygen- O2 These are the basic building elements of all organic material. The human body is organic material and as such, comprises primarily of these three emelents.

Because it is inert and does not react with most of the other elements found on earth.
(NH4)2S % Nitrogen = 41.2 % % Hydrogen = 11.8 % % Sulphur = 47 %
The most abundant elements in Earth are oxygen, silicon, aluminium, iron, calcium, sodium, magnesium, potassium. Other elements' abundance is less than one percent.

Only 4 elements account for 5% of the total and the top 8 elements, combined, account for 99.5 percent.
