Unformatted text preview: Ionization energy? For silicon atoms, which ionization energy will show an exceptionally large increase over the preceding ionization energy? Explain. The 5th ioniztion will require much more energy than the 4th. After the fourth ioniztion, the Si4+ is in a "noble gas" configuration, meaning that it has a full octet of electrons in the outer electron shell. That configuration is very stable, and therefore the atom wants to stay like that, making it hard to remove another electron. 27. Considering successive ionization energies for silicon atoms, which ionization energy value will show an exceptionally large increase over the preceding ionization energy value? A. 2 nd B. 3 rd C. 4 th D. 5 th E. 6 th Si: [Ne]3s 2 3p 2 Thus, the 5 th electron will be coming from the 2 nd shell, while the 1 st 4 came from the 3 rd shell. 16. a. 0.315 g b. 2.99 10 4 m Plasma is the fluid portionof blood. The concentraton of acetylsalicylic acid (aspirin,C9H8O4, molar mass=180 g/mol) in your plasma is found to be 2.99 x10-4M after you take two tablets of aspirin. If the mass=180 g/mol) in your plasma is found to be 2....
