Elements were not found at the same time because they have different properties and reactivities. The discovery of elements was based on experimentation and technological advancements, which allowed scientists to isolate and identify them over time. Additionally, some elements are naturally rare or found in complex compounds, making their discovery more challenging.

What are two factors that contributed to the widespread acceptance of mendeleer's periodic table?
The properties of elements were found to be periodic when arranged in order of atomic mass. The gaps which he left for the elements that were not discovered t that time had same properties when they were discovered later.
Which elements found in nature have mainly radioactive isotopes?
Some elements found in nature that mainly have radioactive isotopes include uranium, thorium, and potassium. These elements have naturally occurring radioactive isotopes that decay over time, releasing energy in the form of radiation.
Are all 109 known elements found in nature?
There are 92 "natural elements, and 21 manmade elements, for a total of 113 elements - all of which exists on earth. You probably learned there are 108 elements, but in the past 2 decades, they have discovered (or made) 5 more. This only means that you probably went to highschool in the early 90s like me.
Who wrote or found the periodic table of elements?
The periodic table of elements was created by Dmitri Mendeleev, a Russian chemist, in 1869. He arranged the elements based on their atomic mass and properties, and left gaps for elements that were yet to be discovered. Over time, new elements were discovered and added to the periodic table by various scientists.
What could you conclude if a dinosaur fossil and a bird fossil were found in the same layer of rocks?
We would conclude that the bird and the dinosaur lived around the same time.
What was unique about the gapes in his periodic table?
The gaps were left for elements which were not discovered at that time. The properties which were estimated for the elements at that time was same as found later in those elements.

Where all the elements discovered at the same time?
No, elements were not all discovered at the same time. Elements have been discovered over time through various scientific methods such as chemical analysis, experimentation, and observation. The periodic table continues to be updated as new elements are discovered.
Where were the materials used to build the great wall of china found?
they werent found, they were bought and paid for. It wasnt a Scavenger hunt in search for materials to build a relatively large wall, it was a process that took time.
