Question:What additional information do we need to answer the question “Which ion has the electron configuration1s22s22p63s23p6”?
Based on their positions in the periodic table, list the following atoms in order of increasing radius: Sr, Ca, Si, Cl.
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: State the Heisenberg uncertainty principle. Describe briefly what the principle implies.
