The objective of this homework assignment is to expand your knowledge of the atom beyond the models presented in General Chemistry 1. To do this you will need to do a little research. Your task is to learn more about the CERN Large Hardon Collider and the research into sub-atomic particles. With that information, you need to teach one of your assigned classmates about one aspect of this research that you find more fascinating. Maybe you are intrigued about the production of man-made elements, or maybe you are intrigued about sub-atomic particles like quarks and the Higgs boson. Take your pick! Can someone please help!!
8 Ionic compounds have high melting points because: A. They are strong conductors of electricity.B. Their crystal lattice energy is high and therefore making it difficult to collapse the solid structure.C. They possess charges that are difficult to disperse on heating D. Heat can not penetrate them properly while inside capillary tubes9 Credits to its discovery goes to James Chadwick, after Schrodinger developed his atomic model:a. Neutron b. Nucleus c. Alpha particlesd. Photons 10 What would happen to an atom in its grounds state if external energy was applied to the electrons?a. Electrons move to an orbital further away from the nucleusb. Atom would be destroyedc. Electrons would be destroyedd. Nucleus becomes supercharged and absorbs the electron.
