# molecule

noun (a molecule, molecules)

«molecule» 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. A molecule is the smallest unit of a substance that still has its properties, made of two or more atoms joined together. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/M/molecule/#m1)
2. A water molecule, for example, is two hydrogen atoms joined to one oxygen atom (H2O). [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/M/molecule/#m2)

### In the lessons

In science lessons molecules come up in states of matter: in solids molecules are packed tightly and vibrate, in liquids they slide past each other, in gases they move fast and far apart; heating makes them move faster. Pupils learn formulas like H2O (water), CO2 (carbon dioxide) and O2 (oxygen). Molecules are much too small to see, even with an ordinary microscope.

### Examples

- A water molecule has three atoms. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/M/molecule/#x1)
- When ice melts, its molecules start to move more freely. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/M/molecule/#x2)
- Oxygen gas is made of molecules with two oxygen atoms. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/M/molecule/#x3)
- Smells reach your nose as tiny molecules floating in the air. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/M/molecule/#x4)
- Heating makes molecules move faster. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/M/molecule/#x5)
- Carbon dioxide molecules are breathed out by animals. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/M/molecule/#x6)
- A single drop of water has more molecules than there are stars we can see. [tree →](https://mova.elamur.ai/free/en/corpora/dictionaries/school/M/molecule/#x7)

### Note

Plural «molecules». Say «MOL-ih-kyool». Adjective «molecular». An atom is a single particle of an element; a molecule is atoms joined together. Not all substances are made of molecules (metals and salt are made differently), but at primary level «particles» is often used for all of them.
