What elements have been discovered since newlands' times?
Since John Newlands proposed his octaves in the 1860s, several elements have been discovered, including those in the lanthanide and actinide series, as well as synthetic elements like technetium, francium, and all the transuranium elements up to oganesson (element 118). Additionally, elements such as gallium, germanium, and scandium were identified after Newlands' time. Advancements in nuclear physics and chemistry have led to the synthesis of heavier elements that were not known during Newlands' era.
What was the reason of the failure of newland octaves?
His work could not get much recognition as no space was considered for undisovered element.The noble gases were also not known at that time.
What are newland's law of octaves defect?
Newlands published the "law of octaves" twice. His first publication was not well regarded because it only included about 17 of the more than 60 elements known at the time. After receiving this reaction, he had a second attempt, trying to fit in all known elements. This was "laughed out of court" at a meeting of the Royal Society because: • the criteria for "chemical similarity" were not well defined nor consistent, leading to some quite bizarre groupings (a lot of obvious "force fitting"). • no allowance was made for possible new elements at a time when the rate of discovery of new elements was around 1 per year. • the law did not arise out of any plausible theoretical treatment. It was purely empirical.
How many elements in Mendeleev table?
Dimitri Mendeleev arranged 63 elements in the periodic table and arranged them according to atomic mass.
Why the relative atomic numbers of some elements are not shown in the periodic table?
All known elements are listed on the periodic table of the elements. Historical tables did not have elements listed that were unknown at the time. For instance, Dimitri Mendeleev, who laid out the first successful periodic table in 1869, did not have any of the noble gases listed since none of them had been discovered at that time. Modern periodic tables have gaps at the lower right end where elements are expected to be created in labs in the future, but have not been successfully created yet.
Which five elements have been discovered between hydrogen and iron since newlands time?
The five elements discovered between hydrogen and iron since Newlands' time are helium, lithium, beryllium, boron, and carbon.

How did John the Baptist become a prophet?
He was predestined by God since the beginning of time to be a prophet
Was there been more than one periodic table?
Yes, there have been several versions of the periodic table developed over time. The current version is based on Dmitri Mendeleev's layout, which arranges elements by their atomic number and chemical properties. Different scientists have made adjustments and improvements to the periodic table as new elements have been discovered.
Was john cena ever in an a tornado?
I love john cena. He's hot and im nine. I had a crush on him since the first time i saw him.
What two elements makes time?
No elements make time.
Is there a biography on Pope John Paul I and II?
There have been several biographies written on John Paul II. A biography on John Paul I may be hard to find since he was Pope for such a short time.

What did Andrew Jackson and john quaicy Adams have against each other?
Since John Quincy Adams was elected the first time, Jackson thought that he had made a bargain to corrupt the election.
Do all elements decay over time?
No, not all elements decay over time. Some elements are stable and do not undergo radioactive decay.
