Which were the elements predicted by Mendeleev and what name did he give them?
Dmitri Mendeleev figured out that there were missing elements on his periodic table. Using periodic trends and averaging numbers, he could make pretty accurate predictions about elements not discovered yet. Mendeleev predicted four: * ekaboron (modern day scandium) * ekaaluminium (modern day gallium) * ekamanganese (modern day technetium) * ekasilicon (modern day germanium)
Could be predicted from the theory of electromagnetic radiation?
Could WHAT be predicted? Please clarify.
Which section was missing on Mendeleev's periodic table?
because they didn't react because they have stable valence shells
What was Dmitri Mendeleev train to be?
he traind to be a fire man so he could train with cemicals so he could what propoteas thay containd!
Was Alfred Wegener blind?
No he was not. If he was how could he have predicted that the continents were once together

How could you use Mendeleevs periodic table to identitify new elements?
He left gaps for the new elements. The properties could be estimated from the space left by him.
Who is the creator of the periodic table and why?
a scientist called Mendelev created the periodic table so that all the elements could be easily arranged by their mass
How could Dmitri Mendeleev predict the properties of elements that had not yet been discovered?
He most probably predicted it. He could have analyzed the table and could have thought there are a lot more elements out there. He probably thought the scientist in his generation did not know all of the elements.
Dmitri Mendeleev was particularly important why?
He is important because he was the person who invented the Periodic Table and made it how it is today
Why are the hydrides of mendeleevs group 1 and 7 placed in separate groups?
Mendeleev left gaps in his table to place elements not known at the time. By looking at the chemical properties and physical properties of the elements next to a gap, he could also predict the properties of these undiscovered elements. For example, Mendeleev predicted the existence of 'eka-silicon', which would fit into a gap next to silicon. The element germanium was discovered later. Its properties were found to be similar to the predicted ones and confirmed Mendeleev's periodic table.
What does the bonding power of an element mean?
Dmitri Mendeleev used the property of bonding power when developing his periodic table. Bonding power refers to the number of bonds an element forms during a chemical change. But Mendeleev could not explain bonding power because he didn't know about the structure of atoms. (search Dmitri Mendeleev's periodic table)
Who created the modern-day periodic table?
Henry Moseley. Dmitri Mendeleev first proposed the periodic table be sorted based on atomic weight. After the discovery of protons, Henry Moseley reordered the table based on atomic number. That is the structure we use today.
Did Mendeleev create 70 elements in the periodic table?
Dmitri Mendeleev was a Russian chemist and inventor. He is credited as being the creator of the first version of the periodic table of elements.Remember the elements are found in nature, using his table he accurately predicted the properties of elements yet to be discovered. For his predicted eight elements, Mendeleev questioned some of the currently accepted atomic weights (they could be measured only with a relatively low accuracy at that time), pointing out that they did not correspond to those suggested by his Periodic Law. He noted that tellurium has a higher atomic weight than iodine, but he placed them in the right order. He was puzzled about where to put the known lanthanides, and predicted the existence of another row to the table. Some people dismissed Mendeleev for predicting that there would be more elements, but he was proven to be correct when Ga (gallium) and Ge (germanium) were found in 1875 and 1886 respectively, fitting perfectly into the two missing spaces.

How hurricane karina could have been predicted?
It was predicted
Which property of bromine could you not predict based on the fact that it is a nonmetal in halogen family?
Bromine is a liquid element. This property cannot be entirely predicted due to its placement on the Periodic Table. The most obvious property that can be predicted is that it is a non metal. But liquidity most certainly is the more difficult of the propertys to predict.
