9. Explain why ionization energy decreases as you move down the noble gases from Helium to argon. 10. Sodium atoms are much larger than chlorine atoms, but sodium ions are much smaller than chloride ions. Why? 11. Compounds have been made from Xenon and Krypton, but not from other noble gases. Give a reason why you think this is true. 12. Based on energy changes involved in forming ions, why does Copper form both Cut and Cu2 ions but Sodium...

You are asked by your instructor to construct a model of the NH_2Cl molecule. Being of a conservative nature, you proceed as directed in the section on Experimental Procedure. First you need to find the number of valence electrons in NH_2Cl_2. For counting purposes with Lewis structures, the number of valence electrons in an atom of a main group element is equal to the last digit in the group...

with others? Oil and water don't mix Gasoline and water also do not mix. However, gasoline and oil do mix. To understand solubility we must look at two important characteristics: geometry and bond polarity (ionic. nonpolar and polar). From these two characteristics the overall molecular polarity can be determined. The statement "like dissolves like" provides a good basis for understanding solubility. A substance with similar characteristics will mix with another substance with similar characteristics. This can be summarized as polar...

1. "Quackism" is a recently discovered element with the symbol Q. It is located in group 7A of the periodic table, in the same group as bromine, chlorine and iodine. How many valence electrons are associated with QO3- ? (I call this e- math in the lecture videos.) Apart from one atom of quackism, the ion also contains 3 oxygen atoms. Also, please take note of the very small negative sign on the formula of the compound. 2. "Quackism" is...
