Well for this questions the method used by scientist are tecnicaly different than others well most suit of what atoms they could find in their place so its easier. But most do say that they put a chemical and if it bubbles its a mixture and if their are no ubble it is a pure substance
Yes, its true because they believed that everything living needed air
The alchemists were the first chemists. But in addition to mixing chemicals, they also believed that magic would help with their experiments and formulas. It didn't. But their experiments led to the development of the science of chemistry.
Cobalt was discovered in Sweden. It was discovered by George Brandt in 1735. Brandt was attempting to prove that the ability of certain minerals to color glass blue was due to an unknown element and not to bismuth, as was commonly believed at the time.
55 Cancri e That is a planet discovered in 2004 orbiting the star 55 Cancri. Its mass is about eight times the mass of Earth, and more than one third of it is believed to be diamond.
Dalton believed that all elements were composed of tiny indivisible particles called atoms. We now know that this is not true, there are particles found within the atom: protons, neutrons, & electrons. Dalton believed that all atoms of the same element were identical. We know this is not true. Isotopes are atoms of the same elemtn that have different mass numbers because of different numbers of neutrons, therefore, all atoms of the same element are NOT identical

Thales of Miletus, who flourished in the 6th century B.C., believed that all things are (or derive from) water. More on Thales can be found in Aristotle's Metaphysics.
they believed that whales had legs and one whale was found with a small leg but it was discovered that a chinese farmer put the leg in the whale skeleton

The Noble gases were known as inert gases because it was believed that they were completely unreactive. This is no longer true as scientists have discovered compounds containing noble gas elements.
People once believed that noble gases couldn't chemically react at all. For this reason, they were called inert gases. They were also clustered under Group 0 in the old periodic table because scientists believed that the gases have zero valence electrons in their outer shell. This was later proven to be untrue when some noble gas compounds were discovered.
In 2008, scientists discovered the fossils of an animal they believed was an ancestor of today's whales. The unique feature of this animal was that it had legs and possible spent a lot of time on land as well as in the water.
As far as it is known to the date, Benjamin Franklin did not work with other scientists. Even if he is famous for having worked in many areas of knowledge (from electricity to politics), Benjamin Franklin is believed to have done everything on his own.

The (cell) nucleus is generally believed to have been discovered by Antonie van Leeuwenhoek. The nucleus of the atom was discovered by Ernest Rutherford.
The first Moari believed to have discovered New Zealand was a man named 'Kope'.
