Consider Si, S, and P.1) Based purely on ideas of electron screening and effective nuclear charge, which of these elements do you expect to have the highest first ionization energy?2) Based on experimental data, P has the highest first ionization energy. Explain this observation in terms of electron configuration arguments.
Explain why the rows in the periodic table become progressively longer as we move down the table. For example, the first row contains two elements, the second and third rows each contain eight elements, and the fourth and fifth rows each contain 18 elements.
The periodic table is the most important organizing principle in chemistry. There is a regular progression in the periodic table that reflects a similar regularity in the structures and properties of the different elements. If you know the properties of any one element in a group, you can make a good guess at the properties
of every other element in the same group and even the elements in neighboring groups. Familiarizing yourself with the structure and arrangement of the periodic table early on will help you later on in chemistry.
