How do you predict if a covalent compound will be polar or nonpolar based on the elements' positions on the periodic table?
Yes
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.
What did Dmitri Mendeleev find when he organized the elements by mass?
I believe the correct answer is he was able to predict the existence of yet undiscovered elements, due to the gaps. For instance, I believe germanium was one of the elements undiscovered in the table, its placeholder was called ekasilicon.
Predict the formula and name of a binary compound formed from the elements with the symbols B and O?
Boron trioxide
Using the periodic table predict how many outer level electrons will be in elements 114 116 and 118?

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.
What does a periodic table predict?
A periodic table can predict elements that are not yet confirmed or identified.
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.
How do you predict an elements group?
they have same numbers of electrons.
How did many elements did Mendeleev predict would be discovered?

Who arrange the elements according to atomic mass and use the arrangement to predict the properties of missing elements?
Dmitri Mendeleev
How can you use the arrangement of elements in the periodic table to predict how they will react with other elements to form compounds?
bc the valence e-
How did the Chinese predict political and military events?
mixing the five basic elements
What information is used to predict chemical reactivity?
The electronegativity of the elements help this prediction.
What is the important work of Dmitri Mendeleev?
Mendeleev was the inventor of the Periodic Table. He organized all the known elements into the periodic table based on atomic number. He was also able to predict the existence of elements that had not yet been discovered based on gaps in the table he created. Based on observations of other elements in the groups he was also able to predict the characteristics of these unknown elements as well. NICE! dude
Who created the first version of the modern periodic table of elements and used it to predict undiscovered elements?
Dmitri Mendeleev
How did the Chinese predict major political and military events?
mixing the five basic elements
