Isotopes‚ sub-atomic particles and relative atomic mass Sub-atomic particles A subatomic particle is a particle smaller than an atom: it may be elementary or composite. In 1905‚ Albert Einstein demonstrated the physical reality of the photons‚ hypothesized by Max Planck in 1900‚ in order to solve the problem of black body radiation in thermodynamics. In 1874‚ G. Johnstone Stoney postulated a minimum unit of electrical charge‚ for which he suggested the name electron in 1891. In 1897‚ J. J. Thomson confirmed

The procedure provided was used with only one change and one correction. The procedure calls for 3 or 4 drops of water to dissolve the dye on the M&M candies but 7 drops were used for each pair of candies because there wasn’t enough water in 4 drops to efficiently dissolve the dyes; the YouTube video for this step from the procedure also showed an application of about 7 drops. The traced solvent front line in this case was not a straight line but a curve with a maximum on 3.2in and minimum on 2.48in

NARY A DROP TO DRINK Water is all around us. This substance is of high importance to every living thing which is on planet earth. As much as we consider water to be life and the most important substance‚ still we don’t seem to appreciate it very much‚ as it is being wasted in such great amounts. Everyone believes that water will always be around but not taking into account that the majority of the water on planet earth are not for human consumption. Human beings can only survive on consuming

The song I chose to analyze was “Drops of Jupiter” by Train. I first heard the song when I fifteen years old. I was warming up in my dance class‚ and as soon as I heard the first verse‚ I immediately fell in love. I never listened to any songs from Train or have been interested in this genre of music‚ but this song has been in my playlist for as long as I can remember. Everyone interprets a song differently‚ but I believe this was meant to be a love song. Beneath the catchy lyrics and upbeat rhythm

was soaked in water before each drop. Procedure To setup the experiment we had to use three meter sticks and two standard tennis balls. We took all three of the meter sticks aligning them vertically up against the wall. Taping them into place we were then able to use them to measure the height of the dropping point. Using our eye sight we had to determine how far up the ball bounced up on the meter stick. We then proceeded to find three appropriate heights to drop then tennis ball at. Dropping it

Determination of Trace Amount of Copper and Zinc in an Aqueous Solution by Atomic Absorbance Spectroscopy Abstract: The purpose of this experiment is to analyze a sample containing copper and zinc in trace amounts‚ where standard addition method was used and the instrument used is the atomic absorbance spectroscopy. The amount of copper obtained was 0.569 ppm ± 0.015 and for zinc we obtained 0.42 ppm ± 0.0027. Introduction: This method implies the excitation of particles in the solution sample

The Development of the Atomic Theory Have you ever wondered how the atomic theory came to be? Or have you have wondered who it was that helped in its development? There was not just one man who came up with the atomic theory‚ but there were many scientists that contributed to its development. One of these scientists was Democritus‚ a Greek philosopher. Democritus was the son of Hegesistratus‚ and he was a student of Magians and Chaldaeans. By some authorities he was thought of as the greatest
