Final answer:

The unabbreviated electron configuration for aluminum (Al) is 1s² 2s² 2p¶ 3s² 3p¹, and the abbreviated electron configuration for titanium (Ti) is [Ar] 3d² 4s².

Step-by-step explanation:

To write the unabbreviated electron configuration for aluminum (Al), which has an atomic number of 13, we start with the first energy level and move up. The configuration is 1s2 2s2 2p6 3s2 3p1.

For the abbreviated electron configuration of titanium (Ti), with an atomic number of 22, we use the preceding noble gas in the periodic table to represent inner-shell electrons. The configuration is [Ar] 3d2 4s2.
