Alexander Shulgin‚ world renowned biochemist is quoted asking “...but the important question is‚ what isn’t DMT in?”. Its described well by Dr. Rick Strassman‚ the only scientist given permission to study it in the last 40 years as; “The Spirit Molecule”. Many believe this substance‚ which flows through every human’s veins may be a link between the mundane world and spiritual world. DMT use‚ albeit nothing like the pure substance that is used today has been traced back to 8th century Chili

particles called atom. He tried to break down matters into smallest particles. His model was that the matter would stop splitting in halves when it reaches its smallest matter. He called that an atom. * John Dalton In 1803‚ John Dalton proposed a theory. The theory had 4 parts into it. 1. Elements are made of identical atoms. 2. Atoms of different elements are physically different 3. Compounds are formed by a combination of two or more different kinds of atoms. 4. A chemical

Introduction: The periodic is a table of the elements‚ organized in order of increasing atomic number. Elements that have similar chemical properties and electronic structures appear in vertical columns‚ or also called groups. The Periodic Law states that when elements are placed in order of increasing atomic number‚ their physical and chemical properties display a periodic pattern. The purpose of the lab was to discover how two periodic properties‚ atomic radius‚ and first ionization energy‚ vary

1: The atom Introduction Atoms are the building blocks for matter Everything is made up of atoms 1A: Sub-atomic particles Atoms are made up of 3 sub-atomic particles‚ 2 of which are located in the nucleus (the heart of the atom) Positively charges protons and neutrally charged (non-charged) neutrons are found in the nucleus Negatively charged electrons are located orbiting the nucleus in shells. They stay in orbit because the electrons are attracted to the protons 2: The Element

Describe the general trend or patterns that you observed in the atomic radius as you go across the periodic table. (2 points) It looks like the atomic radius is bigger if the atomic number is small. This may be because of the decrease of the pull that the protons give the electrons the smaller the atomic number.2. In Part
