Does the periodic table explain the shell model or does the shell model explain the periodic table?
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.
What group of elements in the periodic table is made up of elements that are gases at room temperature?
The elements in column 18 of a wide form periodic table or Column VIII of a narrow form periodic table, commonly called the noble gases. Also, both elements in the first period, the elements in groups 15, 16, and 17 of the second period, and the element in group 17 of the third period.

What does the halogen from the third period mean?
If you have a periodic table of the elements available, look at the second column from the right. Those elements are often referred to as "halogens". The "rows" in the periodic table are often referred to as the "periods". So the halogen from the third period would be "CL", or chlorine. Glad to help with your homework.
Period in chemistry?
A period is a horizontal row on the periodic table of the elements. There are seven periods on the periodic table. Each period corresponds to the highest energy level that contains electrons. For example, the elements in the first period have electrons in the first energy level, which is the only energy level available; the elements in the second period have their highest energy electrons in the second energy level; the elements in the third period have their highest energy electrons in the third energy level, and so on.
