This report will compare the water quality of Freshwater Creek over the last three years using chemistry to show how the three chosen parameters are all linked and affect the overall quality of the water. Water is combination of two atoms, oxygen and hydrogen. When two hydrogen’s bond with one oxygen it makes a covalent bond. A covalent bond relates to the outer shell of electrons (valence shell) being shared with the neighbouring molecule for them to bond. A covalent bond only occurs between…

rest. Keeping with the idea, as the uppermost member of the Halogen Family, fluorine claims the atomic number 9.Though that statement in itself may not seem impressive, the atomic number of fluorine officially describes the nine units of positive charge, called protons, that correspond with nine units of negatively charged electrons. The electrons alone allow fluorine its embellishment, but the protons and electrons together provide stability for fluorine through the creation of neutral…

Ion is a group of atoms which they behave on an electrical charge; there are two types of ions; cation and anion. Cation is a positively charged ion whereas Anion is a negatively charged ion. First ionisation energy- The first ionisation energy is the energy to remove electrons that are unstable from 1 mole of gaseous atoms to gain 1 mole of gaseous ions with a positively charge (1+) As you go down a group, the energy decreases from the top to the bottom due to the shielding effect. When there…

Results and dissection 3.1 Transition metal complexes of the macrocyclic, H6L Ligand 3.1.1 The macrocyclic, H6L Ligand The physical and analytical data of the macrocyclic, H6L ligand and its transition metal complexes were shown in Table 1. From the investigation, the expected structure of H6L with its possible toutomeric forms can be represented as shown in Figure 1. H6L ligand is highly symmetric under the point group C2v symmetry and can show all the normal modes of vibrations by solving…

What is a circuit? How do they work? An electric circuit is a kind of path made up of wires that allows the flow of electrons. The circuit has to be made in a circular form, as the electrons must frequently move in a full loop, in which they will return to their original position and then complete the loop again. (“What is an electric circuit?”) The battery or another source of power provides the voltage, or ‘electrical push’, that makes the electrons move through the circuit. When the electrons…

galvanic cell and is related to the oxidation or the discharge of electrons into the external circuit in the main into the solution. • The anode attracts electrons or anions from the cathode or the electrolyte. • The associate anode may be a supply of charge or work as an negatron acceptor. 2) The…

behaves as Insulator 3. Define electrical conductivity. Electrical conductivity is the ability to conduct an electric current. 4. What are the two types of charge carriers in semiconductors? Electrons and holes are the two types of charge carriers in semiconductor. 5. Define charge carrier. Charge carrier is a particle, which carries electric charge or electric current from one place to another place. 6. Define hole. The absence of electron in the atomic shell is called a hole. 7. Define…

makes vibrations. These vibrations are then made into sound. Another device that utilizes is the MRI (magnetic resonance imaging) machine. MRI devices use powerful doughnut-shaped electromagnets to create a magnetic field around a patient’s body. The charges in the atoms of the patient’s body respond to the magnetic field. Computers measure the reactions and make them into pictures. The pictures are then used by doctors to diagnose medical conditions (Lynette,…

Lithium is the chemical element of atomic number 3, a soft silver-white metal. It is the lightest of the alkali metals. The two main parts of every atom are neutrons and protons. The three main subatomic particles that form an atom are protons, neutrons, and electrons. Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center…

Topic 1: Chemical bonding 1.True or False: An Ion is when an atom gains or loses an electron. 2.What is a Cation? An ion with a (+) charge. 3.True or False: An Anion does not have a (-) charge. 4.What type of bonding transfers electrons? Ionic bonding 5.What are all the types of chemical bonds? Ionic, Covalent, and Metallic bonding. 6.What do you call an element that has different forms . Isotopes 7.Which type of bonding is the “strongest”? Ionic bonding 8.True or False: Ionic bonds are formed…
