Who improved the periodic table?
Dmitri Mendeleev is credited with creating the first version of the periodic table in 1869. Mendeleev arranged the elements by atomic mass and predicted the properties of undiscovered elements. Subsequent scientists, such as Henry Moseley, contributed to refining and organizing the periodic table based on atomic number.
How would global communication between scientists have been changed if IUPAC had not been established?
If IUPAC had not been established the global communication between scientists would have been harder, more confusing, and time consuming. IUPAC is simply a system that helps name chemical compounds.
How did the chemists change mendeleevs periodic table?
Well.... one of the many changes that were made to the periodic table was its appearance. It was coloured in in order for people to recognise the different groups. Red for Group 1, orange for Group 2 etc... Hope this helps. Jeremy Eric Slazkowski, Des Moines, Iowa The Periodic Table was first constructed around 1870 when the Russian chemist Dmitry Mendeleyev catalogued all of the known elements. The elements were arranged according to their similarities. More recently discovered elements were added, and the order of elements became based on their atomic numbers. The modern periodic table has much of the same information as the original one by Mendeleyev, but is arranged somewhat like a chart with elements having similar properties falling into columns called groups or families.
When naming a compound with two elements the ending of the second element is changed to?
The ending of the second element in a compound is typically changed to "-ide". For example, in sodium chloride, the second element chlorine becomes chloride.
When elements combine to form compounds their properties change?
The chemical properties of atoms are significantly changed when they form compounds. When elements combine to form compounds it is called a chemical reaction. The compound is then a collection of molecules and each molecule has are still the same atoms as one started with, but the arrangement of the electrons in the atoms has changed.
When Mendeleev changed the lay out there were gaps how did the gaps help scientists looking for undiscovered element?
The gaps in Mendeleev's periodic table allowed scientists to predict the properties of unknown elements that should fill those positions based on the trends observed in the table. This guided their search for these undiscovered elements by providing a roadmap to their characteristics. This led to the discovery of new elements such as gallium, germanium, and scandium.
What changed the age of exploration?
The Age of Exploration ended when the undiscovered lands had been discovered.

When elements form bonds it changes their properties?
The properties of the elements are changed.
How can elements be changed into compounds?
Elements become compounds after chemical reactions.
Why do you think that scientists have changed the classification system since it was first developed?
I think that scientists have changed the classification system since it was first developed because, the world has grew example technology and they wanted to update it. I also think scientists have changed the classification system since it was first developed to make it easier.
What did dimitri do with the periodic table of elements?
he changed it
Has polonium and radium changed at all?
Being radioactive and unstable elements they are continuously changed.
Why have scientists changed their views about electricity?
they have because they found energy cells
