The elements in each row or period all share the same number of electron shells. The elements in the following period have one electron shell.

(37) The elements in the next period have two electron shells.

The elements in each row or PERIOD all share the same number of ELECTRON SHELLS (36).

To determine the number of electron shells for an element, you can refer to its position on the periodic table. The periodic table is organized in rows called periods. Each period represents a different energy shell level.

The elements in the following period have TWO electron shells (37). This means that all the elements in that period have two energy levels or electron shells surrounding their atomic nuclei.

The elements in the next period have THREE electron shells. Since the subsequent period is one row below, the number of electron shells increases by one compared to the previous period.

Based on the given information, we can fill in the missing words as follows:

The elements in each row or PERIOD all share the same number of ELECTRON SHELLS (36).

The elements in the following PERIOD have TWO electron shells (37).

The elements in the next PERIOD have THREE electron shells.

The elements in each row or period all share the same number of electron shells. The elements in the following period have three electron shells. The elements in the next period have two electron shells.
