Here's why:

* Malleability refers to a metal's ability to be hammered or pressed into thin sheets without breaking.

* Gold is the most malleable metal, meaning it can be stretched and flattened into incredibly thin sheets.

* Silver is also very malleable, but not as much as gold.

* Copper is less malleable than silver.

* Sodium is a soft metal, but it's not considered malleable in the same way as the others because it reacts with air and water.
