Electronegativity

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 more electronegativity. Water is a polar molecule due to the fact that its positive and negative charges are distributed unevenly. It’s the atomic nucleus that gives the positive charge, and the negative charge comes from the electrons. Polarity is determined…

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…

Chemistry ERT - ITEM 3 Item 3.1 and 3.2 – Graphs The trend for the number of electrons in the valence shell for an element is clearly seen in this graph. The lowest point of each peak coincides with the Group I alkali metals. From there on, the electron count climbs until a full shell is reached at eight electrons, i.e. the noble gases who have full outer shells. The full shell signals the end of a Period at Group VIII, and then it begins again in Group I in a new Period. There is…

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…

Investigating Properties Lab Ishan Godra SCH4U Lab Partner(s): DeSean Lawrence Ms. Boulougouris 10/31/14 Purpose The purpose of this experiment is to analyze the properties of four different types of solids: ionic, polar covalent, non polar covalent, and metallic Hypothesis It is hypothesized the samples which are shown to be insoluble are likely non polar, while soluble samples are polar. Because of the molecular nature of each type of bond, it is hypothesized that polar…

Electronegativity helps to explain polar molecules and the differences in ionic and covalent bonding.5, 6 Pauling went on to introduce two new concepts bond-orbital hybridisation and bond resonance both to help explain covalent bonding. Bond-orbital hybridisation…

these differences. Since salts are ionically bonded, they have different properties and functions compared to the covalent bonded molecules. Salts have a ionic bond, and we can confirm due to their electronegativity. As you move from left to right on the periodic table you would notice that electronegativity increases. This is because of the pull the protons have while they try to keep their valence electrons close to themselves. As you go down the periodic table, it decreases because of the…

higher the element on the periodic table the more reactive they will be. Explain how the trend in reactivity is related to the trends in electronegativity and atomic radii down a group. The higher the electronegativity and the smaller the atomic radii the more reactive the element will be when compare to elements with higher atomic radii and lower electronegativity. What results would you expect if fluorine water and potassium fluoride were available to test? Predict what would occur in the…

1. Iodide proved to be the more reactive nucleophile in this reaction. This nucleophile was faster than Chloride, because on the periodic table, Iodine has a bigger atomic size, while Chlorine has the higher electronegativity, but size trumps electronegativity, as according to ARIO rules. This means that Iodine is more acidic than Chlorine, which means that in the reaction, the Iodide could displace the Bromine from the 1-bromooctane, because it has a bigger size, much faster than the Chloride,…

by the intramolecular forces, which are the internal forces of a molecule, such as the attraction and repulsion of electrons to the protons in the nucleus. The external forces on a molecule, which are called the intermolecular forces, such as electronegativity, help to determine the boiling and melting points of each element. Each of these intermolecular forces differs in strength, but even the strongest one is weaker than the intramolecular forces on a molecule. These melting and boiling points…
