You are off to a good start - you've successfully selected the elements you will need.

Now, you need to use the attr method to add an attribute.

$(".external").attr('nameOfAttribute', 'attributeValue');

For example if I did this:

$(".external").attr('name', 'link');

All those a tags would become

<a href="http://google.com" class="external" name="link"></a>

Although it doesn't make much sense in this example, I just use it to provide an example of what the attr() method does.
