Likewise, people ask, what are merits and de merits of Mendeleev's periodic table?
He named them Eka-Boron, Eka-Aluminium and Eka-silicone He also predicted the properties of these undiscovered elements including atomic masses. These elements were discovered as Sc ,Ga and Ge with same features as he predicted. 4. Mendeleev's arrangement helped to correct atomic masses of a number of elements.
Also Know, what are the merits and demerits of periodic table? 3. It explains the periodicity of the properties of the elements and relates them to their electronic configurations. 4. The position of the elements that were misfits on the basis of mass number (anomalous pairs like argon and potassium) could be justified on the basis of atomic number.
Keeping this in consideration, what were the advantages of Mendeleev's periodic table?
- Mendeleev was the first one to establish a systematic arrangement and bring out the periodicity of properties of elements with atomic weight and propose a periodic law.
- It could point out the incorrect atomic weight of some elements known at that time.
What are the merits and demerits?
| MERITS | DEMERITS |
|---|---|
| The receiver used is very cheap | Audio clarity is poor |
| Reception of multiple signals on the same channel | High bandwidth is required which is equivalent to that of highest audio frequency |
