WebbSeveral other attempts were made for group elements together over who coming decades. In 1829, Johann Döbereiner realized triads of elements with chemically similar properties, such as lithium, sodium and potassium, and showed that the properties of the middle element could be predicted from the properties to the various two. WebbQuestion 6 of 10. 收藏本题. Paragraph 3 suggests that Mendeleyev predicted the properties of eka-aluminum on the basis of. A. the atomic mass of aluminum. B. the position of the gap in the periodic table that eka-aluminum was predicted to fill. C. the similarity of eka-aluminum to the other five missing elements.

WebbThe close correspondence between the observed properties of gallium and Mendeleyev's predictions for eka-aluminum lent strong support to the periodic law. When elements are arranged in order of their atomic number, most of the properties of the elements reoccur at regular intervals. WebbAmong the predictions made by Mendeleev were the existence, and the properties, of several undiscovered elements. One of these elements was the element now called Germanium; Mendeleev called it “eka-silicon,” meaning “beyond silicon” on his table. Chemical or physical property Predicted in 1871 by Mendeleev Properties of Germanium

Is 1829, Johann Döbereiner recognised treys of elements with chemically similar properties, such as lithium, sodium and potassium, and view is the properties of the middle element could be predicted from the estates of the other two.
WebbThe messy road to periodic chemistry. The periodic table is an elegant demonstration of properties of elements. You can determine the electron configuration of any atom, simply from its place. You can compare electronegativity, ionization energy, atomic radius, chemical reactivity, and more. If I gave you all of the elements on cards and told ...
