Chapter 6: Q17 E (page 333)
What does it mean to say that the energy of the electrons in an atom is quantized?
When you say that the energy of the electrons in an atom is quantized, it means that each electron has a specific energy level. And they move from one energy level to another.

Compare both the numbers of protons and electrons present in each to rank the following ions in order of
increasing radius:\({\bf{A}}{{\bf{s}}^{{\bf{3}}--}},{\rm{ }}{\bf{B}}{{\bf{r}}^--},{\rm{ }}{{\bf{K}}^ + },{\rm{ }}{\bf{M}}{{\bf{g}}^{{\bf{2}} + }}\).
Question:Read the labels of several commercial products and identify monatomic ions of at least six main groupelements contained in the products. Write the complete electron configurations of these cations and anions.
Question:Consider the orbitals shown here in the outline.
