Groups consist of elements listed in the same column. These elements share similar chemical properties, such as number of valence electrons. Periods are the rows of elements. These elements do not share chemical properties, as periods are organized by increasing atomic number (number of protons).
The horizontal rows are known as periods. The vertical columns are known as groups / families.
Modern periodic table has 7 periods and 18 groups.
7 periods and 12 groups
The Periodic Table has 7 periods (horizontal rows) and 18 groups. The two groups of 14 elements at the bottom (lanthanides and actinides) are parts of the 6th and 7th periods, between groups 2 and 3, but are placed below to limit the displayed width of the table.
the difference between groups (also known as families) and periods is: a group is a column and a period goes across the table remember that
Within-group differences refer to variations that exist among individuals or data points within the same group or category. This can include differences in characteristics, behaviors, or outcomes within the group. Between-group differences refer to variations that exist between different groups or categories. This can include differences in averages, distributions, or patterns observed when comparing multiple groups.
The horizontal rows are known as periods. The vertical columns are known as groups / families.
Not all of the differences that exist between minority groups are due to heredity. Many of the differences are individual, and still others are social constructed.
The columns are called groups and rows are called periods. There are 18 groups and 7 periods.
Only their wavelengths are different.

The "periods" in a big number are the groups of 3 digits between the commas. The correct way to write this big number is: 645,165,758 ... in 3 periods.
