What is the name of the scientist who first developed the periodic table?
You can mainly blame the Russian chemist Dmitri Mendeleyev (or Mendeleev, or Mendeleyef - there are many different spellings of his name.)Back in the early 19th century, a German chemist named Johann Dobereiner noticed that some of the elements fitted naturally into groups of three, called triads, with similar chemical and physical properties. The English chemist John Newlands was the first to notice that if you arranged the elements in order of atomic mass, they seemed to have similar physical and chemical properties every eight elements. He called this the law of octaves, because the way in which these properties repeated every eight elements was similar to the way the same note was repeated every eight notes (octave) on a piano. However, at times his scheme broke down, and he realised there was something wrong with it, abandoning the octave idea. His fellow chemists mocked him for it - someone once said he'd have better luck listing the elements in alphabetical order and looking for patterns!It was Mendeleyev who in 1859 took Newlands' idea of looking for repeated properuties in the elements, and decided to create a table of elements in increasing atomic mass. Unlike Newlands, he left gaps where the pattern did not fit, and predicted new elements would be discovered, predicting their properties from the table. These elements were subsequently discovered, and since then, Mendeleyev's periodic table has been the most useful chart in chemistry.
What are the three elements of electricity?
The three elements of electricity are: - Voltage - Current - Resistance
What are the two elements of stratification?
Stratification has three elements. These three elements are property, power, and prestige. It can be predicted what part a person plays in a social hierarchy based on whether they have these elements and how they portray them.
What three elements were named after the same place?
Einsteinium, Lawrencium, and Californium are three elements that were named after the same place.

Movement Control, Mode Operations, Terminal Operations

What does Faber say the three missing elements in a workd without books and what fo they mean?
Faber believes that the three missing elements in a world without books are quality of information, leisure to digest it, and the right to carry out actions based on what we learn. He implies that without books, our society lacks depth in knowledge, the time to reflect on it, and the agency to act upon it.

What did dimitri mendeleev recognize in 1869?
On March 6, 1869, Mendeleev made a formal presentation to the Russian Chemical Society, entitled The Dependence between the Properties of the Atomic Weights of the Elements, which described elements according to both weight and valence. _________________________________________________________________________ In1869, Mendeleev published the first periodic table. Within 16 years, chemists discovered the three missing elements scandium, gallium, and germanium. Their properties are close to those that Mendeleev had predicted.Over all he discovered the three new or missing elements.
What were the three missing elements in the periodic table?
See "Mendeleev's predicted elements" in Wikipedia The answers are: scandium (Sc - 21), gallium (Ga - 31), technetium (Tc - 43), and germanium (Ge - 32) He temporarily named them to be: ekaboron (Eb), ekaaluminium (El), ekamanganese (Em), and ekasilicon (Es).
