The table you are referring to is likely the Geologic Time Scale. It divides Earth's history into different time periods based on significant events and changes in the planet's geology, climate, and life forms. These time periods are typically grouped into eons, eras, periods, epochs, and ages.
Period 4 and period 5 of the periodic table have the same number of elements. There are 18 elements in each period. While some elements in period 4 are calcium, iron, and zinc, elements in period 5 are tin, antimony, and iodine.
In the periodic table, the horizontal rows are called periods and the vertical columns are groups. Iodine is in period 5.

The water table acts as the boundary between the aeration zone and saturation zone. Below the water table, the pores are fully saturated with water, while above the water table, there is both air and water in the soil pores.
