- 1) Explain how g orbitals are different from s, p, d, and f atomic orbitals? - determine the number of g orbitals that will exist in a given energy level? - include a set of quantum numbers (n, l, and ml) for one of the g orbitals in the lowest energy set of g orbitals? 2) TlF3 forms a stable compound, while the similar compounds TlCl3 and TlBr3 are unstable and undergo disproportionation. Explain why the fluoro compound is more stable than the chloro and boromo compounds?What if there are a different number of Neutrons? Sometimes elements have a different number of neutrons than usual, so therefore have a different atomic mass. This is what we call an Isotope (a variant form of an element which has the same number of protons but a differing number of neutrons). Sometimes we’ll see Isotopes labeled with their new mass like this: 14C = this is Carbon 14. Notice it has a different mass than what is on your periodic table The average mass of all the isotopes is defined as an element’s Atomic Weight. Can you answer questions about these Isotopes? ELEMENT ATOMIC MASS NUMBER OF PROTONS NUMBER OF NEUTRONS 14C A B C 15N D E F 2H G H I Use your table to look up the number of protons, remember that never changes!The elements oxygen and sulfur have similar chemical properties because they both have six electrons in their outermost electron shells. Indeed, both elements form molecules with two hydrogen atoms, water (H2O) and hydrogen sulfide (H2S). Surprisingly, at room temperature, water is a liquid, yet H2S is a gas, despite sulfur being much larger and heavier than oxygen. Explain why this might be the case.
