The element plutonium was named after the dwarf planet Pluto. Plutonium was discovered in 1940, the same year that Pluto was discovered, and both were named in honor of the Roman god of the underworld, Pluto.
Oxycodone was first synthesized in 1916 in Germany by Friedrich Sertürner, who was a German pharmacist. It was later introduced in the United States in 1939, where it was marketed under the brand name OxyContin.
This is an age old question. Philosophers and scientists have theorized for years, and research is still being conducted at places such as CERN in Switzerland. Google the term "God Particle". For the purposes of a high-school or first year college course, it is an atom. But know that this is not true. Atoms or composed of electrons, protons, and neutrons, which are all also composed of components, and so forth.
Methane gas is produced by the decay of vegetation in the absence of oxygen. This process occurs in environments like wetlands or landfills where organic matter decomposes anaerobically. Methane is a potent greenhouse gas with more than 20 times the warming potential of carbon dioxide over a 100-year period.
Francium is a chemical element, its atomic number is 87 and its symbol is Fr. It's a metal that is highly radioactive. It was discovered by French scientist Marguerite Perey in the year 1939. Perey worked at the Curie Institute in Paris, France, she first named the new element 'Actinium-K', later she proposed the name 'Catium', but after finding opposition to it, she proposed the name 'Francium', after France, the name was accepted in the year 1949 by the International Union of Pure and Applied Chemistry.

Democritus formulated his atomic theory in the 5th century B.C. He proposed that all matter is made up of tiny, indivisible particles called atoms. His ideas laid the foundation for modern atomic theory.
The first atomic model was proposed by the Greek philosopher Democritus in 442 BC.
yes, it doesn't really matter how old the person is.
Democritus was an ancient Greek philosopher who lived around the 5th century BCE. He is known for his development of the atomistic theory of the universe, which proposed that everything is made up of tiny, indivisible particles called atoms. However, it is important to note that Democritus did not invent the concept of atoms; rather, he expanded on earlier ideas from philosophers like Leucippus.
It does not matter on that year as long as it is a good name brand.
Aristotle did not discover atomic theory; instead, he rejected it in favor of his own ideas about matter. The concept of atomic theory is more commonly attributed to ancient Greek philosophers like Democritus and Leucippus, who proposed that matter is composed of indivisible particles called atoms around the 5th century BCE. Aristotle, active from 384 to 322 BCE, believed in the four elements (earth, water, air, and fire) rather than a particulate model of matter.
No. If you really love him, age does not matter.
