# atom

noun (an atom, atoms)

«atom» in the English dictionary: everyday and in Jewish tradition — its meanings, how the lessons use it, and examples, each with its tree on Mova.

## Everyday

1. An atom is the smallest piece of a chemical element, far too small to see even with an ordinary microscope; everything around us is made of atoms. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#m1)
2. An atom has a tiny centre called the nucleus, with even tinier electrons moving around it. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#m2)
3. (figurative) «Not an atom of» means not even the tiniest bit: «not an atom of truth». [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#m3)
4. To atoms means into tiny broken pieces, as when something is smashed to bits. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#m4)

### In the lessons

In science lessons atoms come in materials and chemistry: atoms join together to make molecules (two hydrogen atoms and one oxygen atom make a water molecule), and different kinds of atom are the elements on the periodic table, like carbon, oxygen and gold. Phrases: «atom bomb» (a nuclear bomb), «split the atom». Atoms are so small that millions would fit across the full stop at the end of this sentence.

### Examples

- Everything is made of tiny atoms. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#x1)
- A water molecule has two hydrogen atoms and one oxygen atom. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#x2)
- Gold is made only of gold atoms. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#x3)
- An atom is mostly empty space. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#x4)
- Scientists use special microscopes to see the shapes of atoms. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#x5)
- The word «atom» comes from a Greek word meaning «cannot be cut». [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#x6)
- There wasn't an atom of doubt in her mind. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#x7)
- In a moment the witch had the bridge shivered to atoms, and then she hastened away to the palace. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/A/atom/#x8)

### Note

Plural «atoms»; use «an atom» because it starts with a vowel sound. Adjective «atomic». Trap: the name means «uncuttable», but atoms can be split into smaller parts (protons, neutrons, electrons). An atom is not a cell: cells are in living things and are made of billions of atoms. Do not confuse atom and molecule: a molecule is two or more atoms joined.
