Why do you think scientists might have been frustrated by the organization of the elements before 1869?
At that time, scientists knew some of the properties of more than 60 elements. However, no one had organized the elements according to these properties; making it harder for scientists to understand how elements interact with each other.
How many Scientific Elements are there?
There are so many elements that have been discovered. In the world, there are currently 118 different known elements known to scientists.
Do compounds of different elements have similar properties?
Generally the properties are different.
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.
Why are atoms arranged in periods?
Because this arrangement of chemical elements is rational, satisfy the need of classification in chemistry and is very important for the study of chemical and physical properties of chemical elements, including the new discovered or prepared elements.
How many elements have scientist discovered or created?
As of 2006, scientists know of 117 different elements
How many different elements scientists have discovered and studied?
What is a positive atomic partical

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 does the statement the properties of salt are different from the properties of the elements that make them mean?
he properties of salts are different from the properties of elements that go into making them
What does the arrangement of the periodic table help table scientists see?
Patterns in the elements’ properties. -Apex
Which model is use by scientists to determine the properties of elements?
punnett square
what does the arrangement of the periodic table scientists see?
Patterns in the elements' properties
Why do different elements have different properties?
Elements have different properties because elements can be further divided than atoms and can be mixed by another element
Do compounds of different elements have similar properties?
Generally the properties are different.
What did scientist discover when they arranged elements in order of increasing atomic mass?
they discovers a repeating pattern of properties
