## 6.2. Atoms

Atoms are the most basic elements of expressions in AVAP. The simplest atoms are identifiers or literals. Forms enclosed in parentheses, brackets, or braces are also syntactically categorized as atoms. The syntax for atoms is:

```javascript
atom ::= identifier | literal | enclosure 
enclosure ::= parenth_form | list_display | dict_display | set_display | generator_expression
```
