In one of his experiments, Lavoisier used a magnifying glass to focus the sun's rays on a diamond and saw the diamond burn and disappear.He noticed the diamond combined with oxygen to form carbon dioxide which led him to conclude that diamond and charcoal were both made from carbon.These make up the vast majority of its observable mass, dwarfing all the heavier elements combined (and by a wide margin).And between the two, helium is the second lightest and second most abundant element, being present in about 24% of observable Universe’s elemental mass.Unstable atomic nuclei will spontaneously decompose to form nuclei with higher stability. The energy and particles which are released during the decomposition process are called radiation.When unstable nuclei decompose in nature, the process is referred to as natural radioactivity.This event, which lasted from 10 seconds to 20 minutes after the Big Bang, was characterized by the production of nuclei other than the lightest isotope of hydrogen (i.e. All other heavier elements were created much later, as a result of stellar nucleosynthesis.

While in Guntur, India, Janssen observed a solar eclipse through a prism, whereupon he noticed a bright yellow spectral line (at 587.49 nanometers) emanating from the chromosphere of the Sun.

When a beta particle is ejected, a neutron in the nucleus is converted to a proton, so the mass number of the nucleus is unchanged, but the atomic number increases by one unit.



Some of the important tips are to keep it positive and not to reveal too much or too little about yourself. I generally spend my weekends playing soccer with my friends, or watching soccer matches (with/without them), visiting art galleries and hunting for more paintings to buy, and trying new dishes.… continue reading »
