    In the chemistry universe we have many different tools to differentiate and to help identify a substance. The smallest particle of matter is the atom. An atom has the same chemical particles as a whole sample of the element. Everything in the world is made up of these tiny particles called atoms. Growing on our knowledge of the atom, if you combine two atoms chemically you produce a compound. The two different classifications of compounds include organic compounds or those that contain carbon atoms. An example of an organic compound is proteins, fats, carbohydrates, nucleic acids, and other compounds in living organisms. All other compounds are inorganic. Chemist produce compounds in many different ways. Combining elements forms some elements. The compound known as NaCl or table salt is made up of the elements sodium and Chlorine and has very different properties than the individual elements. Sodium is a soft alkali metal and reacts very violently when exposed to moisture and other substances. Chlorine on the other hand is a yellow gas that is poisonous. When these two separate elements are joined chemically they produce a hard, unreactive, white crystalline solid. Compounds also are grouped on which elements make them up. Ionic compounds are made up of a non-metal and a metal. An example of an ionic compound is Potassium Chloride. There are also molecular compounds, or covalent compounds, and these are made up of non-metals. An example is Carbon Dioxide. In chemistry…

    Electron Motion Control and Imaging M. Th. Hassan Electron motion in atomic systems, which happens on timescales of attoseconds (10-18s), is at the heart of all phenomena in nature. For instance, the motion of electrons in the chemical bonds determines the structure change in the molecules. Therefore, controlling this fast electron motion, in turn, allows to control the molecular structure change. Additionally, recording snapshots of the electron motion will provide real-time access to all…

    Chickpea Experiment

    • 4 Pages

    Since the NaCl compound has a molecular weight of 58.44 g/mol and water has a molecular mass of 18.01 g/mol, this shows that NaCl is a bigger molecule. The chickpeas surface undergoes osmosis, allowing for water and/or salt to move from a higher concentration in the surroundings to a lower concentration into the chickpea. Due to the size of the salt molecule, the chickpea will take in less NaCl molecules compared to water molecules to occupy the same space in the chickpea. Figure 2 is a graph of…

    Free radicals are molecules that have at least one unpaired electron. They are typically very reactive, due to their odd number of electrons. These molecules tend to try and gain or lose electrons so their highest energy levels can be filled. They will bond with other compounds in the body, sometimes combining with them, or even taking parts of intact molecules, resulting in even more free radicals (Walling). Free radicals can be formed by natural body processes, such as metabolism. They…

    Stereochemistry Synthesis

    • 8 Pages

    Introduction Stereochemistry alludes to the science that reviews the properties of stereoisomers. It can likewise be characterized as the branch of chemistry concerned about the three-dimensional course of action of particles and atoms and the impact of this on concoction responses. A critical branch of stereochemistry is the investigation of chiral atoms. Stereochemistry is otherwise called 3D science in light of the fact that the prefix "stereo-" signifies "three-dimensionality". The primary…

    think that. How does this make you feel? Normal, I do not really feel bad for that, technically nothing changes. In other words, I just know more about something that was all the time there. If you could touch something, what would you touch? Water, if for instance the atoms repulsion affect the textures of the objects, I really curios which is the real texture of the water. How do you think it would feel? I think it will feel similar, but with more density. This could be similar like…

    resulting in the positive charges on the carbon atom C28.Moreover, all hydrogen atoms have a net positive charge in doped fullerene with alanine. Particularly, the charges on H21 atoms exhibit large positive values 0.3691(RHF) and 0.3053(DFT) for B doped fullerene with L-Alanine and 0.4369(RHF), 0.3805(DFT) for Si doped fullerene with alanine is due to the large negative charge accumulated on the N20 atom. The positive and negative atomic charge suggests the formation of intramolecular…

    It would be ideal to know the interactions between functional groups and how they can be used to potentially increase inhibition efficiency. A possible approach to predicting the characteristics of chemical structures is through the use of quantum chemistry. Frontier orbitals are the predominant force that determines reactivity within a molecule and can be chemically composed to meet certain requirements. The best corrosion inhibitors typically have electron-rich functional groups such as…

    carry out its job and that determines its functions and properties. Structure of water Water the molecule In a water molecule, there is one oxygen that has six valence electrons in its outer shell and acts as the central atom. Two of these electrons is shared with the two hydrogen atoms which have one valance electron each in their outer shell giving a chemical formula of H2O. This shared pair helps to fill…

    with the neighbouring molecule for them to bond. A covalent bond only occurs between two non-metals, the molecules share electrons to achieve full valence shells for the molecule to be stable. In the case of water the two hydrogens and one oxygen share electrons to get the hydrogen molecules with two electrons in their outer shells and…
