Correct option is A
The correct answer is (A) To give the elements positions according to their colour.
Information Booster:
- The classification of elements is done for scientific and logical reasons, such as:
- Understanding the specific position of elements in the periodic table.
- Identifying the periodicity in properties of elements, such as ionization energy, electronegativity, etc.
- Establishing a correlation between the properties of different elements to predict behavior.
- However, classifying elements based on their color is not scientifically relevant or meaningful. The color of elements is not a fundamental property used for classification in the periodic table.
