it because you were such a beautiful silvery transition metal? Or maybe it was your mesmerizing amount of atomic mass… Ya’ know‚ it being 51.996. Are other elements attracted to you because you are simply‚ Odorless‚ tasteless‚ and malleable. Or maybe it’s because you’re used in cars and bikes. Bikes and cars attract the lady elements huh? Not as much as rubies and emerald stones. That’s what you were traced in… Did you know you left some of your clothes there? ‘Cause that vile Magnesium

Spectroscopy Introduction The purpose of the atomic spectroscopy lab experiment was to investigate the relationship between visible light‚ which is the visibly observable range of electromagnetic radiation and the change in energy levels of an element. The line spectrum that was seen in the spectroscope was the evidence of excited atoms emitting electrons and radiating a spectrum of light as it moved from a higher energy state back down to a lower energy level. Using a spectrometer with diffraction

Water: the source of life Water is an indefinable element. It can be destructible and wipe out the strongest forces in the world while it was also the beginning of life. It gives a lot but it can take back more than that. Water is one of the four elements of nature. It’s represented in the liquid form while earth is sold‚ air is gas and fire is the in-between of all. Water is important to every living thing. For plants it’s absorbed from the soil‚ for humans it’s for drinking and use for various

ionGeometric Progression‚ Series & Sums Introduction A geometric sequence is a sequence such that any element after the first is obtained by multiplying the preceding element by a constant called the common ratio which is denoted by r. The common ratio (r) is obtained by dividing any term by the preceding term‚ i.e.‚ where | r | common ratio | | a1 | first term | | a2 | second term | | a3 | third term | | an-1 | the term before the n th term | | an | the n th term |

odourless‚ tasteless‚ soft‚ light yellow solid. It is insoluble in water‚ but is soluble in carbon disulfide. Sulfur is very reactive; it reacts with all metals except gold and platnium‚ forming sulfides. It also forms compounds with various non-metallic elements. Sulfur forms over 30 solid allotropes. Sulfur is a chalogen (group 16 of the periodic table) and a non metal. Sulfur’s atomic weight is 32.06. It has 16 electrons‚ protons and it’s neutrons in it’s isotope is 16. It has a melting point of 115.2*C

How can I find the molar mass of an element?The molar mass of elements is found by looking at the atomic mass of the element on the periodic table. For example‚ if you want to find the molar mass of carbon‚ you would find the atomic mass of carbon on the periodic table‚ and this is equal to the molar mass in grams per mole. So‚ in our example‚ carbon has a molar mass of 12.01 grams per mole.There are a few exceptions to this rule. In some cases‚ the element is usually found in a different form than

role. The next discovery was the atomic theory by John Dalton‚ who at first called the atomic weights “the relative weights of ultimate particles”. His atomic theory was the revolutionary system that described the relationship between atoms and elements. Atoms combining into molecules was another discovery found when Gay Lussac saw that the gases produced twice the volume when combining equal volume of different gases. In 1811‚ Amedeo Avogadro realized that the assumptions that gases remain of single
