How can you predict the properties of missing elements?
yes, properties of an element depends on its atomic number and atomic mass unless it is an exception and the atomic number and atomic mass of unknown elements are known by placing it in periodic table
Meyer contributions to the periodic table are?
Mendeleev developed the periodic table of elements by arranging the elements in order of increasing atomic mass in 1869. He discovered that elements with similar properties occurred in a periodic pattern. He was able to predict the properties of elements that were missing at the time because of this pattern. In 1914, Moseley contributed to the periodic table by reorganizing the elements according to atomic number.
Was Mendeleev's periodic table accurate enough that he was able to use it to predict the existence and several properties of certain elements that had not yet been discovered?
Mendeleev was able to predict the properties of the elements that were not discovered at that time. He left gaps for these elements in his Periodic Table.
What can you use the Periodic Table of Elements for to predict about the elements?
An element's physical and chemical properties. You can also predict what elements will bond with each other.
Who arrenged the elements according to atomic mass and used the arrangement to predict the properties of missing elements?
Mendeleev is usually credited as the first person to do so. Subsequently, chemists learned to arrange the elements by atomic number rather than atomic mass.
Who arrange the elements according to atomic mass and use the arrangement to predict the properties of missing elements?
Dmitri Mendeleev
How did mendeleev make predictions about the properties of elements?
This is a very wordy response, but by setting up the Periodic Table according to elements' properties and characteristics, he was able to predict any given elements' properties because, with the way the Periodic Table is arranged, all of the elements surrounding any specific element would have similar properties to the element that they surrounded. For example, at the time there was no element known as Aluminum, but given the properties of the elements around that area (Group 13), he was able to correctly predict Aluminum's properties. When aluminum was discovered, Mendeleev's predictions were extremely close to the actual element's properties.

How is it possible that mendleev was able to predict the properties of elements that no one knew about?
By looking at the properties of elements he knew about, finding repeating patterns and noticing that there seemed to be elements that were missing from his table. A simple example from maths: What's the missing number in this list? 1, 2, 3, 5, 6, 7... and the answer is: it is 4 and it has the property of being an even number.

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
How could Mendeleevs table be used to predict the properties of elements that had not been discovered?
Comparing the properties of the new element with the properties of the other elements in the group we can make this prediction.
How was the person who devised the first periodic table able to predict the behavior of elements such as gallium scandium and germanium that had not even been discovered yet?
The reason the periodic table was created in the first place was to illustrate the "periodic" physical properties of the known elements of the time. Because of this, the properties of elements that were "missing" from the table could be extrapolated from the periodic trends seen in the known elements.
Did Mendeleev fix the problem of predicted where new elements would fit into the periodic table?
Yes, Dimitri Mendeleev did (accurately, I might add) predict where elements would appear in his table. He also correctly predicted some of the missing elements' properties, based on where they were positioned in his table.
