Final answer:

Group 13 period 5 of the periodic table is indium (In), a post-transition metal with atomic number 49, known for its malleability and fusibility.

Step-by-step explanation:

Group 13 period 5 on the periodic table refers to the fifth element in the column of Group 13 elements. Elements that exhibit similar chemistry are arranged in vertical columns called groups, which are numbered 1-18 from left to right. The seventh horizontal row is called a period.

Group 13 is part of the main-group elements and consists of a mixture of nonmetals at the top and metals at the bottom, also referred to as post-transition metals. The element that is in Group 13 period 5 is indium (In), with atomic number 49. Indium is a post-transition metal known for its softness, malleability, and being easily fusible.

Answer:

Boron is the fifth element of the periodic table (Z=5), located in Group 13. It is classified as a metalloid due it its properties that reflect a combination of both metals and nonmetals. Aluminum (also called Aluminium) is the third most abundant element in the earth's crust.
