...to confuse things, "chord" doesn't mean quite the same here as "guitar chord." It means some notes that you pick out of a scale, then play all at the same time. This is often hard to do on a guitar, but it's very easy on a piano.
And it isn't just any "broken chord," either, you have to play arpeggios in a particular way, starting at the bottom, going up and then coming down again, as you do for a scale. And in the same way as a melody based on a scale is not itself a scale, there are lots of different ways of picking out the notes in a chord, and most of them aren't actually arpeggios.
So, on a guitar or another melody instrument, the easiest way to find arpeggios is often by playing a scale and omitting notes. If you look at BDLH's example, you can see how he has taken a scale of G and made an arpeggio. You play the first note, omit the second, play the third, omit the fourth, play the fifth, then omit the sixth and seventh notes, then play the octave before you come down again. If you start on the third or fifth note instead of the first, you get different kinds of arpeggio, and if you play the seventh note instead of omitting it, you discover a whole heap of new arpeggios, but I think that's enough for now. But just note how the G minor arpeggio is built in the same way as the G major one, only using the minor scale instead.
