What do the long dashes represent on mendeleev's periodic table?
The long dashes on Mendeleev's periodic table represent gaps where elements had not yet been discovered but were predicted to exist based on the periodic pattern of elements. Mendeleev used these gaps to accurately predict the properties of the missing elements, leading to the discovery of new elements.
Does the stairstep pattern on the periodic table of elements represent metals or non-metals?
The stair-step pattern has metalloids on both sides, that is, such elements which possess properties similar to both metals and non-metals.
Why are elements in the tall columns of the periodic table called representative elements?
They follow a pattern for valence electrons.
A chart of the elements showing the repeating pattern of their properties is called the?
the periodic table.
What is the pattern in repeating the properties of elements revealed in the periodic table?
Periodic law,,,
What is the pattern in repeating the properties of elements in the periodic table called?
Periodic law,,,
What is pattern of repeating properties of elements revealed in the periodic table called?
The pattern of repeating properties of elements in the periodic table is called periodicity. This periodicity arises from the similar electronic structure and arrangements of elements within the table.
Who discovered a pattern to the elements of the periodic table in 1869?
Demitri Mendeleev discovered a pattern to the periodic table in 1869.
What is the pattern in repeating the properties of elements in the periodic table known as?
Periodicity, or periodic law.
What is the periodic table (apex)?
A tool to organize the elements
Properties of elements change according to a pattern across the?
