The atomic number increases by one as you go across a row on the periodic table. Each element in the row has one more proton in its nucleus than the previous element, which is reflected in the increase in atomic number. This trend continues across each row of the periodic table.
A horizontal row in the periodic table is called a period. There are seven periods in the periodic table, labeled from 1 to 7. Each period represents the energy levels of the elements within that row.
