As you explore.,answer the followring questions.a.How does adding anatomaffect the position of existing atoms or lone pairs?When you add mere atoms they get closer and closer which causes the bond angle todecrease.b.How does adding alonepair affect the position of existing atoms and lone pairs?The same way as adding an atom., the bond angles decrease2.Is the effect of adding bonded atoms and lonepairsto the central atom similar? Explain whythis could be the case.Yes they are both the same because both take up space, This is because they repel the other electron domain*’We can think of a bond or a lone pair of electrons as a "domain" of electrons. Single bonds.,double bonds, and triple bonds each count as one domain.3.How do the electrons in bends (bending domains) differ from lone pairs (non -bondingdomains)?Electrons in bonds are shared by two atoms while electrons in lone pairs belong to only 1atom.4.What happens to the bond angle when you add or remove an electron domain?The bond angle decreases5. Can you force the atoms into new configurations by pushing atoms around? What does thissuggest about the configuration of atoms in real molecules?Yes you can force the atoms into a new configuration but they don't stay in that configuration.They will adopt to the lowest energy geometry.6.What is the difference betweenElectron Geometryand Afofecufe Geometry?The electron geometry accounts to all domains while the molecule geometry7only accounts for thebonding domains.MOLECULE SHAPES1Preview Mode
