Interpretation: The term “families” in periodic table needs to be explained.

Concept introduction:
A table in chemistry, where all elements are arranged by increasing atomic number is described as periodic table. There are more than 100 elements in the world and the periodic table classifies these elements.

Expert Solution & Answer

Answer to Problem 2RQ

The vertical groups on the periodic table are termed as families because of their similar chemical behavior.

Explanation of Solution

The periodic table is a very useful way to arrange elements. In the periodic table vertical columns are known as families. The properties of elements in vertical groups on the periodic table are similar, just like the characteristics of a particular human family are often similar.

Conclusion

The vertical groups on the periodic table are termed as families.
