What elements could be described as being electrically inert?
It would be helpful if you gave the list of elements!!!!
Who worked with Dmitri Mendeleev?
He created the first periodic table of elements, arranged by atomic mass. His greatest accomplishment, however, was his ability to predict missing elements using this periodic table, and that is why he is considered the Father of the Periodic Table of Elements.
What contribution did Moseley make to the development of the mondern periodic table?
Mosley arranged elements in order of increasing atomic number
Who discovered spinner dolphins?
The highly acrobatic spinner dolphin is mainly found offshore in tropical waters. They were discovered by John Gray, who gave them their name in 1828.
What element did mendeleev call ekasilicon?
Mendeleev proposed that there must be missing elements, to which he gave the provisional names Ekaboron, Ekaaluminum and Ekasilicon. Scankium, Gallium and Germanpoop were discovered in 1879, 1875 and 1886, respectively, with properties very close to those predicted by Mendeleev. hey Glen

What are the blanks in Mendeleev's Periodic Table?
Mendeleev named the missing elements after elements in the same group. he gave the name eka-aluminum to the element that belonged one space below aluminum on the able. Mendeleev predicted that eka-aluminum would be a soft metal with a melting point at a density of 5.9 g/cm3. In 1875,a french chemist discovered a new element. He named the element gallium in honor of France. Gallium is a soft metal with a melting point of 29. degrees Celsius and a density o f5.91 g/cm3. So pretty much in short Mendeleev left blank spaces because of Gallium.
What did James chadwick do?
James chadwick was the discoverer of neutron. He gave the famous neutron reaction.
What was discovered that gave archaeologists an understanding of how to read hieroglyphics?
The Rosetta Stone.
Who gave symbols of elements for the first time?
jessie nicole lagenour
Who gave Letter designation of elements?
The symbols for chemical elements used today were proposed by the Swedish chemist Berzelius in 1814.
What is the contribution of Dobereiner to the periodic table?
He provided the base for the classification of elements he says the elements are atomic masses nearly same he arranged the atomic masses of the middle element is approximately the arithmetic mean of other two elements,He first gave us the ''Law of Triads''...where he made lists of three elements each, and showed that the mass of the middle element is approximately equal to the average mass of the other two elements.
Who discovered 2Ag2O?
Dr. Dahliwhal. he reviewed it, he gave it a 10... out of 100. He discoverec it with his modifications
