My truck ford 2003 won't star?

I already charge the battery. The lights are on but when I turn on the truck there's no sound

Fords are famous for corroding the space between the positive ( red wire ) battery cable clamp & the battery post. Pull that clamp off the battery post & scrape the inside of the clamp & the sides of the post with a small pocket knife blade. If that helps, most all car parts stores carry a small wire brush designed just for that task.

Not much to go on, but I'd guess there's an issue with the solenoid. The solenoid provides power to the starter.
