what are the limitations of newlands law of octaves

 This law could be best applied, only up to the element calcium. Also, newly discovered elemts could not fit into the octave structure and the feature of resemblance of the 8th element when arranged in increasing order of their atomic mass was not successful with heavier elements.

better see it in book......i know but u will get bestlanguage in books

  • -5

this classifiaction was successful only upto the eleents calcium.after that,every eight element did not possess the same properties as by the elements lying above it in the same group

  • -3

it is applicable only till calcium after it every eighth element di not possess properties similar 2 first.

2.) new elements discoverd did not fit into the law.

There were 3 limitations of Newlands law of octaves

i)He could only arrange the then known 56 elementsii)His law was applicable to only Calciumiii)He grouped two element and placed few elements at wrong columns,for example, he arranged Cobalt and Nickle in the column of Flourine, Chlorine and Bromine. He also placed Iron away from Cobalt and Nickle (elements having similar properties

Limitations of newlands law of octaves were:(i) It was not applicable throughout the arrangements. It was applicable up to calciumonly. The properties of the elements listed after calcium showed no resemblance to theproperties of the elements above them.(ii) Those elements that were discovered after Newlands octaves did not follow the lawof octaves.(iii) The position of cobalt and nickel in the group of the elements (F, Cl) of differentproperties could not be explained.(iv) Placing of iron far away from cobalt and nickel, which have similar properties as iron,could also not be explained.

He assumed that only 56 elements were known in nature . When the elements were discovered,they didn't fit into octaves. In order to put all the elements in table, he adjusted two elements in the same slot.

Limitations of law of octaves: The law of octaves has the following limitations ; (A) The law of octaves was found to be applicable only upto calcium. It was not applicable to elements of higher atomic masses. ... (B) Newlands placed two elements in the same slot to fit elements in the table. (C) He assumed that only 52 elements existed in nature 😉

There Are Four Limitations-
1-It Was Not Applicable Throughout The Arrangement
2-It Was Only Applicable Up to Calcium Only.The Properties Of Elements After Calcium Did Not Show Any Resemblance To The Properties Above Them 3-Those Elements Which Were Discovered After Newland's Octave s Did Not Follow The Law Of Octaves.. 4-Placing Of Iron Far Away From Cobalt And Nickel Which Had Similar Properties Could Not Be Explained...

Limitations of newlands law of octaves are as given below :-
(i) The law of octave was found to be applicable only upto calcium. It was not applicable to elements of higher atomic mass.
(ii) Newlands placed two elements in the same slot to fit elements in the table

After discovery of inert gas it was fail

NICE QUESTION... BUT THE BEST ANSWER IS AVAILABLE IN THE TEXT

1) Newland was over confident.He predicted that only 56 elements in our earth.
2) Newland octaves corrected than the calcium. After calcium his table was wrong.
3) Newland put two elements in same gap.

The limitations of Newlands law of octaves are listed below:
- The law was only applicable up to calcium. After calcium the properties of every 8th element were not similar to the 1st element.
- Somewhere he put 2 elements in the same slot like cobalt and nickle.
- The most biggest limitation was that he placed elements having totally different properties with elements which had different properties.
Eg. cobalt and nickle were placed in the group which included elements like chlorine.
- Iron which had same properties as that of cobalt and nickle was placed far away from their group.

I hope you got the explanation! Regards!

1) THE NEWLAND'S LAW OF OCTAVES WAS ONLY VALID UPTO CALCIUM .
2) IT HAD NO ACCOMODATION OF UNDISCOVERED ELEMENTS .

  • This law was not applicable throughout the arrangements.It was only applicable till calcium.
  • Newland assumed that only 56 elements would exist in nature and believed that no more elements would be discovered.However several elements had been discovered n the following years.These elements do not follow the law of octaves.
  • The position of cobalt and nickel could not be explaining according to newlands law of octaves.He kept cobalt and nickel in the same slot.They were placed in the same column as fluorine and chlorine which have complete different properties.
  • The properties of iron are similar to those of cobalt and nickel.However,iron was placed away from them in different column.

1.) The Newlands law of octaves was only applicable up to calcium as after calcium the properties of every eight element was not similar to that of the first element.
2.) Newlands thought that only 56 elements occur in nature and no other elements would be discovered but in future various new elements were discovered which cannot be fitted inside Newlands table.
3.) In order to fit elements inside his table he placed two elements in the same slot but also placed some unlike elements in the same group. For example - cobalt and nickel were placed inside the same slot but were placed in the same note along with fluorine, chlorine and iodine having totally different properties.
4.) He also placed some elements with similar properties to each other in different groups. For example - iron which resembles cobalt and nickel in properties is placed far away from them .
