Given below are two statements :
Statement (I): According to the Law of Octaves, the elements were arranged in the increasing order of their atomic number.
Statement (II): Meyer observed a periodically repeated pattern upon plotting physical properties of certain elements against their respective atomic numbers. In the light of the above statements, choose the correct answer from the options given below :
Statement (II): Meyer observed a periodically repeated pattern upon plotting physical properties of certain elements against their respective atomic numbers. In the light of the above statements, choose the correct answer from the options given below :
Options
- ABoth Statement (I) and Statement (II) are false.
- BBoth Statement (I) and Statement (II) are true.
- C Statement (I) is false but Statement (II) is true.
- D Statement (I) is true but Statement (II) is false.
Correct answer
A. Both Statement (I) and Statement (II) are false.
Step-by-step solution
Law of octaves was arranged in the increasing order of their atomic weight.
Lothar Meyer plotted the physical properties such as atomic volume, melting point and boiling point against atomic weight.
