In 460 B.C. a Greek philosopher, Democritus, developed the idea of atoms. He asked this question: If you break a piece of matter in half, and then break it in half again, how many breaks will you have to make before you can break it no further? Democritus thought that it ended at some point, a smallest possible bit of matter. He called these basic matter particles, atoms, from Greek for "not breakable": a-tomos. (For the meaning of the two word parts, compare English words like "asymmetrical" and "tome".)
In India, a person named Kanaada/Kanada (known as the author of Vaisheshika Darshan) had the same idea, but obviously, he used a different word for the parts: "paramaanu" in Sanskrit, meaning "the ultimate particle". It's not clear when he lived exactly; estimates vary between 6th - 2nd Century BCE
"nucleus"
its not, its closer to about 1/1800 of a hydrogen atom, the English chemist john Dalton was the first person to discover relative atomic masses and use them properly.
You should know this...Protons. Next time, just think about the question! (:
The correct answer would be ground state
This is a chemical element.
The Greeks were the first to use the term atom. Democritus first coined the term Atomos, which is defined as uncuttable. Atoms were based purely on philosophy in Democritus's time.
The ancient Greek philosopher Democritus is credited with being the first person to use the term "atom" to describe the fundamental particles of matter. Democritus proposed that all matter is composed of tiny, indivisible particles called atoms.
