How many transurnic elements are discovered so far?
There are 26 transuranic elements that have been discovered so far. These elements have atomic numbers greater than uranium (92) and are all synthetic, meaning they do not occur naturally on Earth.
Why did Dimitri Mendeleev predict that more elements with specific properties would be discovered?
because,he predicted some possible chemical formulas of the then undiscovered elements between the elements in his periodic table. so he concluded that more elements with specific properties would be discovered.
How many types of element are there in periodic table?
Three: nonmetals, semimetals (or metalloids), and metals.
How many how many electrons does sodium have?
A Sodium atom has three shells. For future reference, this can be discovered later by looking at which period an element falls in. For example, all group 1 elements have 1 shell, all group 2 elements have two shells, and so on.
Did Mendeleev leave gaps in the table for undiscovered elements?
Yes, Mendeleev left gaps in his periodic table for undiscovered elements. He predicted the properties of these missing elements based on the trends in the known elements and their positions in the table. This helped in the discovery of elements such as gallium, scandium, and germanium.
How many elements were there in 1860?
63 elements had been discovered so far.
How many transurnic elements are discovered so far?
There are 26 transuranic elements that have been discovered so far. These elements have atomic numbers greater than uranium (92) and are all synthetic, meaning they do not occur naturally on Earth.
How many elements are there in the extended periodic table?
The discovered elements all are not complete, so there are the extended ones. They currently go up to number 173, or unsepttrium
How many elements are currently in the periodic table?
there are about 125 or120 and some haven't even been discovered yet. so there's a good number of elements in the periodic table
What new elements were discovered?
Take a look at a periodic table. All elements after Uranium were discovered fairly recently, within the last 100 years or so. Some others, such as Technetium and Francium, were also discovered in that time.Take a look at a periodic table.

How many elements are there in total?
117 know ones (some are yet to be discovered)
Why were so many elements discovered in the 1800s?
About 70 elements had been discovered by the mid-1800s.
Why did Dimitri Mendeleev predict that more elements with specific properties would be discovered?

How many Scientific Elements are there?
There are currently 118 known elements on the periodic table, with elements ranging from hydrogen (atomic number 1) to oganesson (atomic number 118). These elements are organized based on their atomic number and properties, and each element has its own unique characteristics.
Who discovered more number of elements in science?
It was Albert Ghiorso who discovered or co-discovered the most elements, 12.As a member of both the Manhattan Project, and later a researcher at UC Berkeley, Ghiorso and his teams uncovered elements 95 (americium) through 106 (seaborgium). All of them are radioactive; and all of them are man-made, having long since decayed in nature.Of them, americium has seen the greatest commercial use, being found in most modern smoke detectors.
