# How to calculate the average valency for a lattice

## Objective:

Learn how to calculate the average valency for a lattice

## Procedure:

**1. Create your lattice**

To calculate this, you need to use one of the new [Beta](/help-articles/knowledge-base/user-interface/what-are-beta-blocks) lattice blocks. In this example, we are starting with a **Voronoi Volume Lattice** block.

**2. Extract the Property chips**

* Open up the Properties of the **Voronoi Volume Lattice** block by clicking the question mark icon.
  * Expand the **"Lattice"** property and then expand the **"beams"**
  * Expand the **"> Properties"** chevron underneath the **"beams"**
  * Drag out the **"end point valency"** chip and the **"start point valency chip"** into the Notebook section.

**3. Combine the Lists**

* Add a **Concatenate List** block
  * Insert the two property chips, **"end point valency"** and **"start point valency"**, into the inputs

**4. Calculate the Average**

* Add an **Average** block
  * Delete the auto-populated list
  * Insert the **Concatenate List** block
  * Select the Overload to change the type to Scalar List
  * The average valency now appears at the top right of the block

And that's it! You've successfully calculated the average valency of your lattice.
