Teoria y Estructura Atómica The Periodic Table of Elements III: Electron configuration por Katie Grace Carpenter, M.S. Lectura Prueba Enseñe con esto Use the periodic table to answer questions 4 and 6. image ©Visionlearning 1. Though exceptions exist, elements in the same column as carbon would be expected to form the same number of bonds. true false 2. All electron shells have an s-type and a p-type subshell. true false 3. Knowing an element's electron configuration can help you to predict____. the maximum number of chemical bonds an atom of that element is likely to form. what color that element would likely appear in its elemental form. what year that element was discovered. the frequency with which that element occurs in Earth's crust. 4. Based on the periodic table, would you predict calcium (Ca) or oxygen (O) to have more electrons in the valence shell? Use the periodic table above to answer this question. Ca O Unable to predict from periodicity trends. O and Ca are equal in this respect 5. Which of the following subshells would fill up first? 1p 3s 2p 2s 6. Which of the following elements would achieve a noble gas electron configuration by gaining two electrons? Use the periodic table above to answer this question. Nitrogen (N) Oxygen (O) Neon (Ne) Magnesium (Mg) 7. An electron orbital is just another word for an individual electron. true false 8. Who is credited with first connecting carbon's high bond capacity with its ability to form the backbone of biological molecules? Dimitri Mendeleev Rhonda Levin August Kekulé Niels Bohr 9. What is electron affinity? The energy change that occurs from adding an electron to an atom. The energy that is gained from adding an electron to an atom. The energy change that comes from removing an electron from an atom. The energy that is lost by removing an electron from an atom. 10. Why was structure-based drug design such a powerful tool for researchers developing the world's first anti-HIV drugs? This technology allowed scientists to synthesize the first HIV proteins in a lab. This technology allowed scientists to model thousands of hypothetical molecules that might be able to disable crucial HIV proteins. This technology provided tools for creating many different types of molecules in the lab that could be tested on rats. This technology helped researchers develop a complete genetic profile for various strains of HIV. Resultados de Prueba
