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.
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.
