The Chemistry talk

             The discovery of the atom, proton, neutron, and electron were significant turning points in the history of science. Sub-atomic particles are classified into elementary particles and composite particles. Elementary particles are composed of quarks, which comprise protons and neutrons. Composite particles are composed of protons, neutrons, mesons, baryons, and neutrons, each composed of two up quarks and one down quark. Subatomic particles have numerous applications in daily life. As our knowledge of these particles deepens, future applications of subatomic particles are likely to increase. A fundamental on Atom and sub-atomic particles: ·               Atoms are the fundamental units of matter. Protons, neutrons, and electrons are the three subatomic building blocks that make them up. The atom's nucleus contains positively charged protons, which are particles. ·     ...

Atom and Mass Concept In the context of physics and chemistry, "atom" and "mass" are fundamental concepts that play a crucial role in understanding the structure and behaviour of matter. 1.      Atom : An atom is the basic unit of matter, and it constitutes the building blocks of all chemical elements. Atoms are incredibly small and cannot be seen by the naked eye. They are composed of even smaller subatomic particles, mainly protons, neutrons, and electrons. Protons : Positively charged particles found in the nucleus (centre) of the atom. Neutrons : Particles with no charge (neutral) are also found in the nucleus. Electrons : Negatively charged particles that orbit around the nucleus in energy levels or shells. The number of protons in the nucleus determines the element's identity, as each element has a unique number of protons. For example, an atom with one proton is hydrogen, while an atom with six protons is carbon. The total number of protons and neutrons i...

  Climate change is the study of negative chemical processes in the Earth's environment caused by human activities like vehicular emission, industrial pollution etc. The important elements that damage the environment are as follows. The greenhouse gasses :  The climate system of Earth's is significantly affected by greenhouse gasses which are identified as GHGs. Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and fluorinated gasses. The greenhouse effect, which is caused by these gasses trapping heat in the Earth's atmosphere, is crucial to keeping the planet's temperature habitable. But the activities of humans like deforestation, burning fossil fuels, and industrial processes, have dramatically increased GHG concentrations,causing global warming. Carbon Cycle:  The carbon cycle  is an important environmental process, in which  exchange of carbon dioxide between the atmosphere, land, and oceans. Human activity, specifically the burning of fossil fue...

  CHROMATOGRAPHY To separate the mixture, a physical method is used, it is chromatography.A mobile phase in which a mixture is dissolved, is passed through  a stationary phase.During this, different components of the mixture travel through the stationary phase at different rates, depending on their affinity and solubility for the stationary phase, the components of the mixture are separated. History of Chromatography In the 19th century's 1803, the French botanist Michel-Eugène Chevreul used a process to separate the pigments in plant extracts,termed paper chromatography.However, chromatography was not  began to be developed into a more sophisticated analytical technique till 20th century.  In the year 1900, the Russian botanist Mikhail Tsvet developed a column of powdered alumina to  separate plant pigments. He termed this technique " chromatography ", from the Greek words " chroma "  means " color " and " graphein " means " to write...
