Step by step
Solved in 3 steps with 3 images
- 1. Calculate the effective nuclear charge of the 59th electron in Platinum using slater's rules 2. Give the noble gas electron configuration of Uranium 3. Give the noble gas configuration of Bromiumexplain argon electron affinity according to slaters rules5.Reason from a scientific model. Write out a brief paragraph explaining why we see specific colors when we heat up ionic salts up in a flame. When providing an explanation, make sure to describe the events in the correct order, and specify correctly the cause of a change and the effect of that cause. Describe the Bohr model of the atom and make sure you address the following questions: So a. What is happening to the atoms in the solid salts as they are heated: a) What phase change occurs as you heat the salt? b) Where is the energy coming from for this phase change? b. What is happening to the electrons inside the metal ions to make them generate visible light? 1. Use a Bohr model of an atom to describe the energy changes of the electron required to generate light, starting from the ground state. Why do different atoms produce different colors? All these atoms have the same number of valence electrons, so why do you think their colors are so different? C.
- 3. a) Mg and Al are used as anode materials in X-ray Photoelectron Spectroscopy (XPS). Determine the energy of X-ray photons emitted by Mg and Al atoms when an electron from the 2nd shell fills a hole in the 1st shell and compare with the experimentally observed values for Mg Ka and Al Ka radiation given in the lecture. Use the Bohr model (without correction) when calculating the transition energy.Chemists in the 19th century constructed an evacuated glass tube with wires inserted in both ends. When an electrical current was generated at the anode, a 'cathode ray' would pass to the cathode creating a fluorescent glow. These experiments helped chemists better understand the nature of the electron. J.J. Thomson added a magnetic field to a cathode ray tube to show that the ray would bend. His experiments demonstrated that the rays were negatively charged particles. He then calculated the mass to charge ratio of the electric ion (electron). According to his calculations, how massive was the electron relative to the hydrogen ion? Voltage Source A) The same size B) ~1000 times larger C) ~1000 times smaller + S D) ~10 times larger Anode Cathode E) ~10 times smallerIllustrate the electron spin quantum number of Carbon
- 4. What are the main ideas in the nuclear theory of the atom?In a 1911 paper, Ernest Rutherford said: In order to form some idea of the forces required to deflect an alpha particle through a large angle, consider an atom containing a point positive charge Ze at its center and surrounded by a distribution of negative electricity, – Ze uniformly distributed within a sphere of radius R. Derive an expression for the magnitude of the electric field at the center of the atom. - Express your answer using the parameters +Ze and -Ze.7. Why is Rutherford's model (with electrons orbiting the nucleus like planets around the sun) not necessarily correct? Explain. 1149
- Use Slater's Rules to address these questions • What is the effective nuclear charge for the highest energy electron in F atom? • What is the effective nuclear charge for the highest energy electron in F- atom? • Which is easier to ionize (remove an electron)?Two main-group elements are highlighted in the outline of the Periodic Table below: What can you say about these elements without knowing exactly which they are? Use that knowledge to answer the questions in the following table, if possible. Important: do not try to figure out exactly which elements are marked, and then use your knowledge of the properties of each specific element. You don't need to. You will also be marked wrong for any answer, correct or not, that can't be determined from the rough location of each marked element in the Periodic Table. Element X Element Y Which element in the gas phase is more likely to glow green or yellow in a flame? X 5 O Can't say without more information. O Element X Which element is more likely to form an ionic compound with chlorine? O Element Y O Can't say without more information. O Element X Which element in the solid state is probably brittle, so that it breaks before bending? Element Y Can't say without more information. Explanation Check8.
