The word atom is derived from the ancient Greek adjective atomos, meaning “uncuttable” or “indivisible.” The earliest concepts of the nature of the atom were debated in ancient India and ancient Greece. We now know that the atom has a nucleus composed of protons and neutrons surrounded by clouds of electrons.
In Greek, the prefix “a” means “not” and the word “tomos” means cut. Our word atom therefore comes from atomos, a Greek word meaning uncuttable. Answered by: Dan Milx, Physics Ph.D, York University, Toronto. The word is derived from the Greek word “atomos”, meaning indivisible.

Are atoms positive or negative?
The nucleus has an overall positive charge as it contains the protons. Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
Who named the atom based on the Greek word meaning indivisible?

Does atom meaning indivisible?
An atom is the basic unit of an element. … The Greek root of atom is atomos, which means “indivisible,” since the scientists who first gave the atom its name imagined it couldn’t be split or divided into smaller pieces.
Why is an atom negatively charged?
Protons are tightly bound in the nucleus and can be neither gained nor loss. So any change in the charge of an atom is due to changes in its electron count. If a neutral atom gains electrons, then it will become negatively charged. If a neutral atom loses electrons, then it become positively charged.
Why are atoms called indivisible?
The term “atom” comes from the Greek word for indivisible, because it was once thought that atoms were the smallest things in the universe and could not be divided. We now know that atoms are made up of three particles: protons, neutrons and electrons ā which are composed of even smaller particles, such as quarks.
How are atoms not indivisible?
For instance, we now know that atoms are not indivisibleāas stated in part oneābecause they are made up of protons, neutrons, and electrons. The modern picture of an atom is very different from Dalton’s “solid, massy” particle. … Scientists have even developed the technology to see the world on an atomic level!
Does an atom become positively charged?
A charged atom has either too many or too few electrons. … When one or more electrons is knocked off of an atom, it becomes positively charged. It is now an positive ion. A negative ion can be made by adding an electron to an atom.
What makes an atom positively or negatively charged?
An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom. … If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion.
Who coined the name atomos meaning indivisible?
Democritus
What language is atomos?

What is atomos?
Atomos (Greek “undivided”) may refer to: Atom, a basic unit of matter in science. Atomos, basic unit of matter in theory of Greek philosopher Democritus. Atomos (magician) or Atomus, a Jewish Cypriot magician in Josephus.
How does an atom become positive or negative?
If an atom gains or loses an electron, it bacomes an ion. An atom that gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion. Picture 1.8 Some atoms lose electrons and become positive ions.
Who proved that atoms are not indivisible?
Democritus
