  • Research Paper On Electronegativity

    Electronegativity is based upon the atoms strength within the element to attract electrons to form bonds. Now atoms like to fulfil the octet rule of having a perfect 8 outer shell causing it to be stable. Now unfortunately not all elements have a full outer shell now elements on the left side of the periodic table contain less than half of electrons the required energy to gain electrons is much higher than comparison to trying the energy to lose an electron. So the elements on the left side when they form bonds they actually lose electrons. Now on the right side of the periodic table are much more efficient in energy to gain electrons to form a complete outer shell. When we move across the periodic table from left to right the electronegativity…

  • Interhalogen Synthesis Lab Report

    room temperature. After letting the test tube cool and no more crystals were forming, the ethanol was removed into a waste beaker. ii. Detection of decomposition Approximately 3 mL of distilled water was placed within test tube three to dissolve the crystals. The solution was then transferred into a cuvette used within a UV-Vis spectrometer. After 20 minutes another spectrum was taken giving a second graph. After another 20 minutes, another spectrum was taken giving the third graph. Cleaning the…

  • Paintball Research Paper

    Made). The paintballs or markers are cooled in a cool room. This get the warm moist paintball cooled for hardening purposes. When not hardened correctly, many problems can occur and can cause injury to the players. All paintballs work with different pump guns and air pumps. The markers are manufactured the same way. Paintballs are soluble with polarity and hydrogen bonding.The text states “Water is a polar substance that has distinct regions of positive and negative charge. Water’s polarity is…

  • Organic Chemistry

    This semester, I’m in a course entitled Principles of Chemistry I. Currently, I need to learn and store trends of the periodic table. One particularly hard area is electron affinity and ionization energy trends. Electron affinity is how willing an element is to gain an electron, and ionization energy is how willing the element is to lose an electron. Remembering which direction each of those two trends go on the periodic table has been difficult for me. I’m trying to store this information in my…

  • The Disappearing Spoon Summary

    Sam Kean, a Washington D.C. writer with works in The New York Times Magazine, Mental Floss, Slate, The Believer, Air & Space, Science, and The New Scientist, has created a user-friendly book about how to explain the periodic table and the elements that occupy it by writing the book The Disappearing Spoon: And Other True Tales of Madness, Love and the History of the World From the Periodic Table of Elements. He provides an insight into the world of chemistry that relates to his audience, even…

  • The Principles Of The Octet Rule, Electronegativity, Polarity

    The Chemistry of H2O. Principles of the Octet Rule, Electronegativity, Polarity, Density, and their effect on H2O Aryeh L. Strauss Suny Rockland Atoms are made up of protons, neutrons and electrons. Protons have a positive charge and electrons have a negative charge (neutrons are neutral). The protons are in the nucleus of the atom and the electrons fill shells surrounding the nucleus. The shells closest to the nucleus have the lowest energy level and the shells furthest away have the…

  • Polarity Of Plants Essay

    Plants gain a lot of nutrients in their daily lives. They get it mostly from water and also the soil. Water is a molecule made up of the following atoms, Hydrogen and Oxygen. In this molecule the electrons are not shared equally between these atoms. Electrons are negatively charged so if they spend more time around an atom the atom becomes negative. The electrons turn Oxygen negative because they spend more time together. The reason for the electrons to be around Oxygen is because Oxygen has…

  • Essay On The Periodic Table Of Elements

    The most common periodic trends include atomic radius, electron affinity, electronegativity, ionization energy, melting point, and metallic character. Some of these trends are related to each other, as they are directly related. For example, as shown in figures 3-5, the trends of electronegativity, ionization energy, and electron affinity are directly related. Atomic radius is equal to a half of the distance between the nuclei of two atoms of the same element. When moving down a group on the…

  • Origin Of Water On Earth Essay

    At the water molecule occurs the covalent bond. Hydrogen has an inferior electronegativity compared with oxygen.4 Oxygen attracted the negatively charged electrons, and it makes the oxygen has a negative charge. 4 The opposite applies to hydrogen, and makes it has a positive…

  • Item 3.2 Graph Research Paper

    electron shells closer together than they were before. This is why Atomic Radius decreases as you move across the Period; more protons = more electrons = more nuclear attraction = more closely bound shells = smaller atomic radius. Electronegativity is measurement of its propensity to attract and bond with other atoms, and there is definitely a Period trend involved. Electronegativity increases as you move from left to right across a Period and decreases as you move down a Group.…
