Well, honey, if you swallow lead, it can cause a whole mess of problems like stomach pain, vomiting, and even lead poisoning. So, I suggest you don't go munching on any lead pencils or paint chips like they're a snack. Stick to food, trust me, it's much tastier and safer.
Nothing happens

pain
You can get chemical burns along your throat and stomach if you swallow lye.
You burp bubbles
If you swallow a small piece of mechanical pencil lead, it will likely pass through your digestive system without causing harm. However, swallowing a large amount or if it becomes stuck, it could cause a blockage or injury. It is recommended to seek medical attention if you have any concerns.
I assume you mean Lead. If that is the case go to the hospital, lead is toxic and you may need to have your stomach pumped depending on the amount of lead you ingested. If your talking about pencil lead which is graphite then no harm will come and if you meant l.e.d. than again nothing.
It depends on how much you swallow. If it is a large amount, you could get diarrhea and/or vomit.
You'll choke and die
Your ink drys out.
