A proven truth is a fact or statement that has been verified through evidence, data, or logical reasoning. It is something that is widely accepted as accurate and reliable based on scientific, historical, or empirical research.
NEW (BETTER!) ANSWER Physics endeavors to understand the workings of (inanimate) nature and natural processes in a fundamental and unified way. The keywords 'fundamental' and 'unified' distinguish it from other studies, such as chemistry, biology, empiricism, heuristics, hand waving, palm reading, astrology and witchcraft. OLD ANSWER: [ Physics is the study of matter and energy and the interaction between them. Physicists study such subjects as gravity light and time. Compared to other physical sciences which are Chemistry and Astronomy physics focuses more on matter. Hope I Helped! ]
The existence of atoms was hypothesised, imagined if you like. Their existence is supported by a huge volume of experimental and theoretical evidence, but there is no absolute proof, and probably never will be. Democritus, more than 2000 years ago imagined the existence of atoms.

Yes, some people initially opposed John Dalton's ideas, particularly those related to the concept of atoms and the atomic theory. Some critics argued that his theories lacked sufficient evidence and were too abstract to be proven at the time. However, over time, Dalton's ideas gained acceptance and are now fundamental to modern chemistry.
Alchemy was a pseudo-science that eventually evolved into modern Chemistry, which was simply found and proven to be more right.
Alchemy has been proven not to work. It is sheer fiction.
Because it used magic. Alchemy was abandoned because it didn't work. Some of the things that did work became chemistry. No one successfully turned lead into gold. Nor did anyone successfully create the philosopher's stone. Alchemy was basically chemistry with a lot of magic thrown into it. The alchemists were sorcerer want to be's. They attempted to conjure spirits, and use spells on chemicals that they believed contained magical properties, all in a vain attempt to convert base metals into something of greater value. Even Isaac Newton, probably the greatest scientific mind of the last 500 years, accomplished nothing in alchemy, even though he experimented with it for decades.

Pseudoscience is a claim, belief, or practice which is presented as scientific, but does not adhere to a valid scientific method, lacks supporting evidence or plausibility, cannot be reliably tested, or otherwise lacks scientific status. Alchemy in ancient times became what is known as chemistry in modern times. Since most of the principles can't be proven, it became a pseudoscience.
You can't. Alchemy is a pseudoscience that didn't really work, though it did help pave the way for modern chemistry. Alchemists toyed with various chemical reactions without understanding them. They did not realize that gold is an element and so cannot be produced through chemical means. Nuclear physicists can turn other elements into gold using particle accelerators, but the process costs far more than the value of gold produced.
Alchemists study and practice Alchemy which is considered a protoscience. While Alchemists are real people with a real purpose, the field they practice has not been proven real, as yet, by scientific protocol. Using a loose definition, you could call chemists modern alchemists. But there were real alchemists who's main goal was to change one substance into another, usually this a cheap metal, like lead, into gold. Though the methods were primitive, the concepts are considered important work towards modern chemistry.
Alchemy is generally understood to be the chemical science that predated chemistry. In the modern era, it is generally assessed to be a primitive science centered around men obsessed with a dream of turning lead in to gold. However, alchemy was actually quite similar to chemistry in a number of aspects; and many of the greatest minds in history were alchemists. Isaac Newton, considered to be the father of physics, and Robert Boyle, considered to be the father of chemistry were two prominent alchemists. Alchemy itself is often described as a combination of chemistry and philosophy. To elaborate, they used observation, logical deduction and experimentation in an attempt to understand the world around them. Though they weren't always right, they did lay the foundation for future scientists. Alchemy, like its modern counterpart focused a good deal on the separation and combining of chemicals; which they termed "transmutation". However, they didn't understand the distinction between molecules and atoms as we now do, so they weren't aware that you can't change the structure of an atom as you can with a molecule. Because of this, they believed they could also transmute base materials, such as lead, iron and mercury in to "noble" metals, such as gold, silver and platinum. A number of alchemists became obsessed with this idea, as it was a quick way to get rich if it could be achieved; and because of this, alchemy became associated with that goal. The substance by which they believed they could turn common metals in to noble ones was known as the Philosophers' Stone. Transmutation on an atomic level has been proven possible, but aside from radioactive decay experienced by elements such as uranium, it takes too much energy for transmuting gold to be a viable source of wealth. Alchemists were also medicine men. Many doctors of the era were alchemists. In fact, you can thank the alchemist Paracelsus for a number of modern medicines. He was one of the first scientists to suggest therapy using different chemicals. Though his prescribed cures weren't always helpful, he did lay the foundation for the medicine we use today. Many alchemists, including Paracelsus were searching for a "panacea", or "cure all", which they called the Elixir of Longevity. Because it could cure any ailment, it could make the user virtually immortal; thus the name. To surmise, alchemy was a very imaginative science. Though many of its theories were wrong in comparison to modern knowledge, it did lay the foundation for modern chemistry and medicine.
Not that modern science has proven.
The science of alchemy has been proven false through years of experimentation. In short, you cannot simply create something if you don't have the right materials to do so. You can't just get a sack of dirt and expect it to become a lovely wedding cake.
Yes She Does Has Been Proven
Chemistry is primarily focused with the study of chemicals and how they react with one another, as well as how to create new chemicals through these reactions. Alchemy is a somewhat broader subject. It has often been described as a combination of chemistry and philosophy. Alchemists research was also centered around chemicals, but they also incorporated other subjects, such as religion, physics, metaphysics, art, geometry, and dozens of other fields of research. Because of its various esoteric fields, it is often considered a mystical science, and this is one of the reasons it has become so discredited. Also, alchemists searched for a number of objects that have been deemed an impossibility by modern scientists. Two of the most famous being the Philosophers' Stone, and the Elixir of Longevity. The Elixir of Longevity was a name for the panacea. A substance that could cure any ailment, making the user virtually immortal. The Philosophers' Stone was a substance alchemists believed could transmute common metals in to "noble" metals; one of the favored examples being the ability to turn lead or iron in to gold or silver. However, transmutation has been proven possible in the modern era; but aside from natural radioactive decay, turning other metals in to gold takes far too much energy to be a feasible means of attaining wealth.
