Which of the following statements are true about the emission of visible light when a metal ion is placed into a Bunsen burner flame? Select all that are TRUE. All the cations you test in the flame will produce an emission in the visible range. The heat energy from the burner excites the outermost electron to a higher orbital where it is unstable. A sodium ion will produce a bright yellow flame. O The color observed corresponds to the encrgy difference between electron orbitals.

What is the Noble gas core which represent the core electrons and an orbital diagram to represent the electron configuration for valence electrons for the following? label your orbital diagram clearly for element Mn (#25) and see if each species is paramagnetic or diamagnetic A neutral atom of your element The product ion from Mn^8+(g)=Mn+9(g)+e^- The product ion from Mn^4-(g) +e^-=Mn^5-(g) (fifth electron affinity for element #25). 4. Rank each of the species from smallest to largest radii and explain the ranking using zeff. 1. 2. 3.

Each of the statements below attempts to explain why some periodic property varies predictably among elements in the periodic table. Determine if each statement is true or false. Within a period, elements with higher atomic numbers have atoms of smaller radius because the valance electrons are in higher principal energy levels. Within a family, elements with higher atomic numbers have lower ionization energy because the valance electrons are in higher principal energy levels. Within a period, elements with higher atomic numbers have higher ionization energy because the valance electrons are in higher principal energy levels. Within a family, elements with higher atomic numbers have higher electronegativity because the atoms have higher effective nuclear charge. Within a period, elements with lower atomic numbers require more energy to remove an electron from the atom, because the valance electrons are in higher principal energy levels. Within a period, elements with lower atomic…
