Without its atmosphere, Earth would be
bombarded by meteorites, similar to mars, relatively lifeless. Without the atmosphere objects can just enter the atmosphere and cause serious harm to us, but with the atmosphere it basically reduces damage and shrinks it to size.

The second row of the periodic table reflects second energy level which corresponds to 2 subshells obtained in this row.
Periodic table is arranged in rows and columns, the columns represents the group of the elements and the rows represents the energy level of the elements.
When we observe the second row of the periodic table, we will notice the following;
- The <em>second row</em> of the periodic table corresponds to <em>second energy level.</em>
- The maximum number of shells is <em>2.</em>
- The number of electrons in the second subshell increases from left to right
- The maximum number of electrons in the second subshell is 8, which is found in group zero (noble gases group).
Thus, we can conclude that the second row of the periodic table reflects second energy level which corresponds to 2 subshells obtained in this row.
