Calcium (Ca), strontium (Sr), and barium (Ba) are all located in the same column of the periodic table because they have similar atomic structure and similar chemical properties

Periodic table

From the question, we are to determine why calcium (Ca), strontium (Sr) and barium (Ba) are all located in the same column of the periodic table

The periodic table is a tabular arrangement of chemical elements that is arranged by increasing atomic number and groups elements according to recurring properties.

Elements with similar atomic structure and similar chemical properties appear in the vertical columns. These columns are called groups.

Hence, calcium (Ca), strontium (Sr), and barium (Ba) are all located in the same column of the periodic table because they have similar atomic structure and similar chemical properties
