    two reactions, which is the better nucleophile, chloride ion or bromide ion? Try to explain this. Bromine is a better nucleophile. The chloride ion is more polar since it is above bromine on the periodic table and is more prone to hydrogen bonding due to its smaller size. Chloride ions are worse than bromine ions for nucleophilic attack, because the chloride ions are fully solvated and are not as available to attack. This is why Bromine ion is better nucleophile because is less electronegative and

    Identification of metal ions and inorganic compounds in aqueous solution Introduction: Qualitative analysis is the identification a sample's component(s). Unlike a quantitative analysis, we are not concerned with the amount of a substance present in a sample but only with its identity. In this exercise we will focus on identifying the cations and anions that make up ionic compounds, both solid and in solution. Ideally there would be chemical tests that could be used to identify individual ions without interference

  • Lithium Atomic Structure

    1751 Words  | 8 Pages

    In the periodic table lithium’s atomic number is 3. The atomic number describes the number of protons in the nucleus and the number of electrons in the atom when it is not ionized. (An ion is an atom where the amount of protons and electrons is not equal.) Lithium has 3 protons; therefore it must have 3 electrons when it is not ionized. The protons and neutrons together form the nucleus. Lithium has 3 protons and usually 4 neutrons since its atomic weight is 6.9 according to the periodic table

    Mariel Beauroyre 9-B A chemical bond is form with the joining of two or more atoms (when two atoms are joined they form molecules and compounds.) Which are being held together by the attraction (force attraction) of atoms through sharing as well as exchanging electrons. Chemical bonds are found in molecules, crystals, or in solid metals. They also organized the atoms in order structures. But why are they important you may ask? They’re important because every material or substance in the world

    ionic compound and which are a covalent compound. In order to accurately digest the experiments results, definitions of each relating factor were researched, leading to the following information: ionic compounds are positive and negatively charged ions that experience attraction to each other and pull together in a cluster of ionic bonds; they are the strongest compound, are separated in high temperatures, and can be separated by polar water molecules. A covalent compound is formed when two or more

    as reinforced as an ionic compound, thus it takes less energy to separate. In addition, unknown B has a very low solubility and conductivity, this is due to the atoms sharing electrons, therefore they cannot have the ability to separate and form an ion. However, it should be noted that covalent compounds should most definitely not be conductive or soluble, but the results have shown otherwise, thus it should be concluded that there may have been contamination between the scoopula’s used. Conclusion

  • Hydrate Lab

    840 Words  | 4 Pages

    Due to water’s polar structure, ions in some compounds attract and form bonds with water molecules, forming hydrates. A hydrate is a salt that has water molecules trapped within its crystals. Every hydrate has a certain number of water molecules weakly bonded to the salt as follows: salt • number of water molecules Anhydrous salts are salts that can form hydrates but which have had all the water driven off, usually by heat. By heating the Copper (II) sulphate hydrate until its color changes from

    by either ionic or covalent bonds. IONIC BONDING: Ionic Bonding is the complete transferring of valence electrons between two atoms. This type of chemical bonding results in two oppositely charged ions, a cation and an anion In ionic bonding the electrostatic attraction between the charged ions holds the compound together.

    Unknown White Compound by conducting various test and learning how to use lab techniques. Tests that are used during this experiment were a flame test, ion test, pH test, and conductivity test. The results drawn from these tests confirmed the identity of the Unknown White Compound to be sodium acetate (NaC2H3O2) because there were no presence of ions and sodium has a strong persistent orange color. The compound then will be synthesized with the compounds Na2CO3 and HC2H3O2 to find percent yield. Weighed

    In ionic bonding, once the bond has occurred the atoms become stable and they become ions. Ionic bonds in nature are quite strong. Therefore the ionic compounds have high melting points and can be either very hard or brittle. The materials are good insulators, for both electricity and thermal conditions. These characteristics would be seen

  • Covalent Bonds: Hydrogen Sulfide

    1405 Words  | 6 Pages

    Metals form positive ions and non-metals form negative ions, thus making ionic bonds the electrostatic forces of attraction between oppositely charged ions (BBC, 2014). Ionic bonds transfer valence electrons, from the metal to the non-metal. They tend to have high melting and boiling points since they are very strong and need a lot of energy for the bonds to be broken. Although ions are charged particles, ionic compounds can only conduct electricity if their ions are free to move. They do not

    OBJECTIVE The objective of this experiment was to analyze and determine the unknown concentration of a protein solution by utilizing two different colorimetric techniques; Biuret and Lowry. The Biuret method was used with unknown #2 and the Lowery method was used for unknown #1. After the concentration of each unknown was analyzed (by Biuret or Lowry method), the alternate objective was to compare the results achieved by each method and to determine if the results from the approaches were consistent

  • Pros And Cons Of Halogen Bonding

    2221 Words  | 9 Pages

    Halogen bonding, XB, is the product of a non-covalent interaction between a halogen X and a negative site B (e.g., Lewis base). The halogen, X, is usually part of an R-X molecule where R can be another halogen, an organic or an inorganic electron-donating-group. Halogen bonding (XB) is in some ways analogous to hydrogen bonding (HB). In the latter, a hydrogen atom is shared between an atom, group or molecule that “donates” and another that “accepts” it.[1-3] In halogen bonding, it is a halogen atom

  • Halogens Research Paper

    Halogens belong to group 7 in the periodic table, and are non-metallic elements. The term halogens mean “Salt former” which means that their combinations containing halogens are called Salts. All halogens have 7 electrons in their valence shell, giving them a charge of -1, and only require one electron to become a complete shell. Halogens are very chemically reactive which increases as you move up the periodic table – fluorine being the most active element. Halogens exist in room temperature in all
