What is meant by the term native state?

Explanation

### Step-by-Step Solution:

1. **Definition of Native State**: The term "native state" refers to the condition in which certain metals are found in nature, specifically in their elemental form. This means that these metals exist as pure elements rather than as compounds or ores.

2. **Reactivity of Metals**: Metals that are found in the native state are typically less reactive. This is because they do not readily combine with other elements to form compounds. The reactivity of metals can be understood in relation to their position in the electrochemical series.

3. **Position in Electrochemical Series**: Metals that are located below hydrogen in the electrochemical series are generally less reactive. This lower reactivity allows them to exist in their native state.
