2) Consider this representation of a periodic table:

a. What is the group number of the shaded column?

b. What is the number of outer electrons for a neutral atom of each element of this group?

c. You are observing/comparing how two of the element in this group (remember vertical columns are called groups), would you expect to see similar reactions? Explain.

Expert Solution

a) Please attach the column/group of the periodic table.

b) In general, the groups in the periodic table can be labelled from IA to VIIIA (transition metal series is from IB to VIIB).

For groups from IA to VIIIA: The outer electron configuration is given as- . This involves filling up of the s orbital and then the p orbital. i.e (IA) to (VIII A)

c) Since elements in a group/column have the same number of valence electrons, they will show similar chemical properties/chemical reactions.

Although silicon and carbon are in the same group of the periodic table and do not share the diamond cubic crystal structure (for one polymorph of carbon) but look very different when in the diamond cubic crystal structure compare how the two polymorphs with the diamond cubic crystal structure look (ie compare how silicon looks to how diamond looks)

65. Because carbon and silicon are both elements in group 14 on the periodic table, we expect them to react with other elements in similar ways. To some extent, then do, but in some cases, carbon and silicon compounds that seem to have analogous structures have very different chemical characteristics. For example, carbon tetrachloride, CCl4 is very stable in the presence of water, but silicon tetrachloride, CCl4, reacts quickly with water. The unbalanced equation for this reaction is SiCl4...
