86 F150 need help

1986 F150 doesn't start - I'm pretty sure battery is good because lights come on and stay on. What may be an indicator to someone knowledgeable is what I turn the ignition it makes a quick and loud clicking noise, it makes me think of a machine gun. It isn't chugging or anything, but I just don't know anything about where to start and it is such a distinct noise I would imagine someone might know right away.

Usually that rapid clicking is low/inadequate amps available to hold solonoid engaged for starter. Lights could still work as they don't need as much amperage. A jump should start this and probably needs battery checked out/replaced - check charging system and all connections while you are at it,

What would be the problem if a jump doesn't start it? Is a solenoid another name for a battery or is that something different?

I'm not there, obviously, listening to this but the fluttering/machine gun sound is usually the solonoid not getting enough power to hold the connection of the larger battery positive wire on to the starter. If the noise is much more mechanical grinding it could be the starter grinding on its gear with the flywheel gear.
This vehicle's solonoid should be close to the battery if you follow the positive battery cable. It's spring loaded to be off and the amps must overcome that spring or it won't send full power on to the starter because low amps can hurt a starter motor.
Problems with connections - all of the ones involved with battery cables - six places in this vehicle could need cleaning up. When they are weak you frequently would notice all lights go out and a single click then nothing more.
The battery could be weak because it's just getting old, is run down for some reason, or the charging system is not keeping it fully charged. A jump - and you need to make sure you have a good connection to donor vehicle or device must be good takes the question of the battery's condition out of the picture for just the start so if that works then you would want to know why the battery couldn't do it. If over 3-4 years old they lose their punch and it's worth just replacing it even if not the sole problem right now.
In short: tThe likely problem is the battery isn't powerful enough right now,
