To make it easier to understand‚ we can bring in the five senses and its objects: sight‚ smell‚ taste‚ sound and touch. According to Ayurveda‚ life or existence is not a rigid compartment‚ but a harmonious flow. Even these five elements‚ of which the whole universe is made‚ are not tight compartments of defined objects. They flow into one another. Each one of the elements contains the other four.

determine the elements present in them but they do not give the actual structure or the functional groups present. Since all organic compounds contain hydrogen and carbon‚ most tests consist of only the determination of oxygen‚ sulfur‚ nitrogen and halogens – elements that are most of the time the only ones involved in organic compounds. The experiment focused on the Sodium Fusion test‚ which tested for all elements except oxygen. In the test‚ the test compound is broken down into its elements‚ which then

periodic table. The table is laid out in the order of the atomic weight of each element. He wrote‚ in his book‚ that he arranged every element known to man just by their atomic mass and weight. He understood the science of elements and how they worked better than anyone else of his day. He guessed about future elements‚ as well‚ and what their properties might be. He also provided places for these possible new elements in the periodic table. At the time‚ however‚ a lot of people did not care for

Listed in the periodic table‚ are elements. All elements have a neutral charge‚ or the charge always equal 0. This is why the amount of protons and electrons are the same in every element. Also‚ the relative atomic mass does not include the electrons‚ because their mass is so small‚ it barely makes up the atom. Atomic Number & R.A.M To find the numbers of protons‚ neutrons and electrons of an element‚ we use the atomic number and the relative
