About 70 elements had been discovered by the mid-1800s.
it was a time when greater understanding was obtainable due to increased availability of equipment and materials (industrial revolution)
It was difficult to remember all the properties of the elements because the elements were so disorganized.
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.
This was the time of the California Gold Rush, in which hundreds of thousands of people flocked to California hoping to strike it rich.
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.
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.

There are so many elements that have been discovered. In the world, there are currently 118 different known elements known to scientists.
your mom descovered it

The discovered elements all are not complete, so there are the extended ones. They currently go up to number 173, or unsepttrium
Because some of the elements were not yet discovered so he left them blank for other elements to be discovered. -bobby corner
out of the 118 elements discovered so far, most of them are metals
he predicted that there were elements not yet discovered so yeah.
Element number 6 was one of the first elements discovered, so it is not widely known who discovered it.
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
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.
