Why G7 sounds this way
Why does it sound unfinished? Inside G7, two notes are arguing: B and F. Play the arpeggio again, no rush and catch the second and the last note — the distance between them is the tritone, one of the tensest intervals in tonal music. G and D keep the house standing while those two argue inside it. And an argument, you know, demands a resolution.
How to play G7 on guitar
On the guitar, six strings give the chord room to breathe — some positions use them all, others ask you to mute the lowest ones. So grab the first position below — 3 open strings to help you; it's the main shape — that's why it carries the ⭐. Now the experiment that explains this chord better than any explanation: play G7, hold it for one breath, then play C. Felt the door close? Do it again. That relief is the dominant's job.

Where G7 shows up
Its most common job is the dominant, and dominants live as VII7 in A minor, V7 in C major. Plainly: where it enters, the song is usually about to leave the room. In the blues, though, G7 can also be the home chord. A chart full of 7th chords is a song that won't sit still.

Going beyond G7
For soloing, G Mixolydian (G A B C D E F · 1 2 3 4 5 6 b7: the major scale with a lowered seventh — the blues accent); G Lydian dominant (G A B C# D E F · 1 2 3 #4 5 6 b7: a mixolydian with a raised fourth: the dominant in formalwear) cover the whole chord. And look at the first swap on the list below: that's the famous tritone substitution, the twin dominant living three whole steps from here, the one arrangers reach for when they want to arrive at the same place by a prettier road.
