Periodic Table Groups Vs Periods

Periods 6 and 7 have 32 elements because the two bottom rows that are separated from the rest of the table belong to those periods. Periods in the periodic table in each period (horizontal row), the atomic numbers increase from left […] Usually, either family or group refers to one or more columns of the periodic table.

Characteristics of groups and periods in a periodic table.

Mendeleev’s periodic table has 8 vertical columns called groups and 12 horizontal rows called periods. As with any grid, the periodic table has rows (left to right) and columns (up and down). Both describe elements that share common properties, usually based on the number of valence electrons.

Difference between periods and groups. The periodic table is organized in families and periods. The vertical columns of elements are called groups, or families.

On moving from top to bottom in the periodic table, atomic number and mass number increases. Elements are arranged in order of increasing atomic number, their physical and chemical properties show a periodic pattern. Hence, this is the key difference between periods and groups of the periodic table.

When the elements are thus arranged, there is a recurring pattern called the ‘periodic law’ in their properties, in which elements in the same column (group) have similar properties. Number of columns and rows. Using the periodic table, you can classify the elements in many ways.

The elements in a group have similar physical or chemical characteristics of the outermost electron shells of their atoms (i.e., the same core charge), because. Groups and periods the periodic table is a way of arranging the elements so patterns in their properties and reactions can be identified and explained. One useful way is by metals, nonmetals, and metalloids.
