Newlands observed a pattern in the properties of elements when arranged by increasing Atomic Mass, leading him to propose the Law of Octaves. He noticed that elements with similar chemical properties appeared every eighth element, a concept Dalton did not recognize. This observation highlighted the periodicity of element properties, laying groundwork for later developments in the Periodic Table. Newlands' work emphasized the systematic nature of elemental relationships, which was not fully appreciated by Dalton.
What else can I help you with?
Why didnt helium and neon appear in Newlands table?
Helium and neon did not appear in Newlands' table because they are noble gases, which were not discovered until after Newlands' periodic table had been proposed. The noble gases were not known at the time when Newlands arranged the elements based on their properties.
Where did john Dalton find the atom?
john dalton didnt find the atom democrites did... john dalton was reading and found the word atomos in a journal and decided he would change the name to atom meaning undivisible.
What scientist before mendeleev developed the first ideas of arraging the elements?
Johann Wolfgang Dobereiner arranged them in triads, Alexandre-Emile Beguyer de Chancourtois arranged by atomic weight, John New-lands and William Olding published periodic tables that used atomic weight to arrange the elements into groups with analogous properties, Julius Lothar Meyer is closest to periodic table as it is today he just didnt make predictions about unknown elements like Mendeleev
Why is John Dalton not credited with creating the first theory?
John Dalton is typically not credited with creating the first atomic theory because other scientists before him, such as Democritus and Antoine Lavoisier, had proposed ideas about the atom. Dalton's theory, however, was more comprehensive and backed by experimental evidence, which led to its widespread acceptance in the scientific community.
What did mendeleev do when an element didnt fit the pattern?
When an element didn't fit the pattern in his periodic table, Dmitri Mendeleev prioritized the properties of the elements over their atomic weights. He would leave gaps for undiscovered elements, predicting their properties and placing them where they would fit according to their characteristics. This approach allowed him to maintain the overall organization of the periodic table, leading to the eventual discovery of elements that confirmed his predictions.

he didnt

What happens if we didnt have the periodic table?
Chemistry does not evolve so it should be invented.
How did john newlands discover the periodic table?
Oh, dude, John Newlands didn't exactly "discover" the periodic table like stumbling upon buried treasure. He just noticed that when he arranged elements by atomic weight, every 8th element had similar properties. So, he came up with the Law of Octaves. It was a pretty chill observation, nothing too groundbreaking.

What element usually accept electrons usually have negative valence and are found on the right of the periodic table?
the one u didnt no about!
How can you teach HM fly to your empolion?
you cant if u didnt notice empolions a penguin penguins are FLIGHTLESS birds.
If you run 100 meters in 1 minute how fast are you going?
Oh yeh, thanks. I didnt notice. XD
Are there any Xivio glitches?
Yes There Are Some. Notice: You Asked If They're any glitches you didnt say we had to tell you what the glitches are (:
Can you make out if you have tmj?
i have tmj and i was really worried about the same thing, but when i made out with someone i didnt even notice it so it turns out you can :)
