Elements and symbols in Atoms And Molecules – Class 9 Science Experiment

Chapter Name: Atoms And Molecules

Activity Name: Elements and symbols in Atoms And Molecules

Activity Description:

In this experiment, participants will correct the possible symbols of certain elements listed in Table-3. The objective is to understand the correct representation of elements’ symbols and the reasons behind the correction

Required Items:

  • Table-3 with the list of elements and their possible symbols.

Step by Step Procedure:

  1. Examine Table-3 containing a list of elements and their possible symbols.
  2. Cross-check each symbol with reliable reference sources (e.g., periodic table, chemistry textbooks) to verify its accuracy.
  3. Identify and record the incorrect symbols for each element.
  4. Provide reasons and explanations for the corrections made to each symbol.

Experiment Observations:

  • Participants will observe and document the corrections made to the possible symbols of the listed elements. They will gain insights into the significance of accurate element representation in chemistry.

Note down your observations in table format:
