Why was it difficult to study chemistry in the early 1800s?
It was difficult to remember all the properties of the elements because the elements were so disorganized.
What natural resource was discovered in western Pennsylvania in the mid 1800s?
Oil was first successfully drilled in Pennsylvania near Titusville in 1859. It had been known to exist for a long time before that so it wasn't oil that was discovered but a way to remove it from the ground.
Why did so many people go to California in the 1800s?
This was the time of the California Gold Rush, in which hundreds of thousands of people flocked to California hoping to strike it rich.
What did people think in the 1800s caused day and night?
There was a lot of superstition in the 1800s and many people thought that god caused day and night by looking through a telescope (which was the sun) and every 12 hours would rotate it around the other side of the world so he could see the people on the other side of the equator and with no telescope the was no sun so it was going to be dark.
What did you have to do to become a veterinarian in the 1800s?
There were no specific requirements for becoming a veterinarian in the 1800s. Anyone who wanted to could say he was one, and immediately begin treating animals. The quality of the care varied greatly from one vet to the next, and many of the so-called treatments the animals got were useless, and some were even harmful.
How many elements were there in 1860?
In 1860, there were 92 known elements.
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.

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 elements are there in total?
117 know ones (some are yet to 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.
How many types of element are there in periodic table?
Three: nonmetals, semimetals (or metalloids), and metals.
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.
How many elements have been identified?
the total number of elemetns humanly known is 118
