Groups and periods are two ways of categorizing elements in the periodic table. Periods are horizontal rows (across) the periodic table, while groups are vertical columns (down) the table. Atomic number increases as you move down a group or across a period. Element Groups Elements in a group...
Periodic Table with Group Numbers and Period Numbers Period The periodic table's horizontal row is called a period. The periodic table is divided into seven periods, each starting on the far left. When a new primary energy level begins to fill with electrons, a new period begins. Period 1 ...

Group, in chemistry, a column in the periodic table of the chemical elements. In a group, the chemical elements have atoms with identical valence electron counts and identical valence vacancy counts. Groups are numbered from 1 to 18. Learn more about gro
An important part of chemistry is being able to understand the various useful features of the periodic table of the chemical elements. These features include the atomic number, row position and column position of each element. Each row is a period and each column is a group. All groups are ...
