As you go down the horizontal rows, the energy levels increase.
What is the name of a row going across the periodic table?
A row going across the periodic table is called a period. There are seven periods in the periodic table, each representing a different energy level for the elements within that row.

What are periods and groups?
Periods in the periodic table refer to the rows that categorize elements based on the number of electron shells they have. Groups, on the other hand, are the columns that group elements with similar chemical properties based on the number of electrons in their outermost shell (valence electrons).
