  • Alchemy

    A secret group of people started to search for a philosopher stone for transmuting things (metal) in gold and the elixir of the life, something that gives completely knowledge. They never found these things but they shaped the foundations of chemistry.
  • Iatroquímica

    Iatrochemistry (or chemical medicine) is a branch of both chemistry and medicine. The word "iatro" was the Greek word for "physician" or "medicine." Having its roots in alchemy, iatrochemistry seeks to provide chemical solutions to diseases and medical ailments.
  • Phlogiston teory

    Phlogiston teory
    The phlogiston theory is a superseded scientific theory that postulated that a fire-like element called phlogiston is contained within combustible bodies and released during combustion. The name comes from the Ancient Greek φλογιστόν phlogistón (burning up), from φλόξ phlóx (flame).
  • Periodic table

    Periodic table
    In 1669 German merchant and amateur alchemist Hennig Brand attempted to created a Philosopher’s Stone; an object that supposedly could turn metals into pure gold. After this, all cientists discovered more elements and finaly created the periodic table.
  • Chemistry as a scientific activity

    Chemistry as a scientific activity
    Development of the electric battery
    Atomic theory
    Atomic theory was completed
    It proposed planeshifter problem
    Periodic table
    Theory of relativity
    Elements (radio, Poland)
    Study of the chemical elements
    Studying genetic
    The first cloned organism
    (Every theory must be checked and proved)
  • Chemistry of today

    Chemistry of today
    Chemistry of today is so extensive that it is divided into 5 branches to explain it:
    Organic chemistry: molecules studied by carbon chains.
    Inorganic Chemistry: study minerals and elements from the periodic table.
    Analytical chemistry: study the composition of matter in qualitative and quantitative.
    Biochemistry: study the composition of the six living.
    Physical chemistry: studies matter from the point of physically and chemically.
  • Scientific method

    Scientific method
    Is a research method used mainly in the production of knowledge in science. For being called scientist, a research method should be based on the empirical and measurement, subject to the specific principles of scientific method testing is razonamiento. The cientific method, that has characterized much, consists mainly in systematic observation, measurement, experimentation, formulation, analysis and modification of hypotheses.
  • A 113 element in the periodic table is discover

    A 113 element in the periodic table is discover
    A team of researchers from Japan Riken Center confirmed that they had identified the 113th element of the periodic table, synthetic character and the provisional name uruntrio.
