Why is it that when I got stabbed in the elbow with a pencil in 6th grade, the lead is still in my skin?

Because the lead is not really made of lead, it's made of carbon, which not only reacts with your skin, but also forms a matrical structure that your skin will grow around..Exactly the same way that tattoos will stay in your skin. I have two stab marks from 20 years ago. Did you know that tattoo ink can be made using special inks and charcoal(which is made of carbon)

I stepped on one when I was four....it was a very rusty nail...went right through my right foot, through my slippers first. When  I looked down, the tip of the rusty nail was poking out of my foot. I was rushed to the hospital for a tetanus shot and treatment.

since its not "lead" anymore, its not poisonous at all, if its bothering you go to the dr, if its not...It can really be left there, I had done the same thing when I was 10 yrs old, I can still see the spot where I jabbed myself lol

What are you asking here?  If there is an equation for the half-reactions of a pencil dipped in cupric chloride solution?  If so, it is easy, since there is no reaction.\n\nCuCl2 ============> Cu2+  + 2 Cl-  in solution\n\nPencil lead  = graphite and clay.  No ions in solution.\n\nThus, no reaction.\n\nOTOH, if you are referring to lead ions in solution (say, from lead nitrate) then you get:\n\nCuCl2 + Pb2+ ===========> PbCl2(s) + Cu2+\nThe half-reactions are:\n\nCuCl2 ===========> Cu2+  + 2 Cl-\nPb(NO3)2 ==========> Pb2+  + 2 NO3-\nPb2+  + 2Cl- ============> PbCl2 (s)\n\nThe copper ions and nitrate ions would remain in solution.

Pencils are made industrially by mixing finely ground graphite and clay powders, adding water, forming long spaghetti-like strings, and firing them in a kiln. The resulting strings are dipped in oil or molten wax which seeps into the tiny holes of the material, resulting in smoother writing. A juniper or incense-cedar plank with several long parallel grooves is cut to make something called a slat, and the graphite/clay strings are inserted into the grooves. Another grooved plank is glued on top, and the whole thing is then cut into individual pencils, which are then varnished or painted.\n\nMany pencils, particularly those used by artists, are labelled on the European system using a scale from "H" (for hardness) to "B" (for blackness), as well as "F" (for fine point). The standard writing pencil is "HB". However, artist's pencils can vary widely in order to provide a range of marks for different visual effects on the page. A set of art pencils ranging from a very hard, light-marking pencil to a very soft, black-marking pencil usually ranges from hardest to softest as follows:\n\n9H 8H 7H 6H 5H 4H 3H 2H H F HB B 2B 3B 4B 5B 6B 7B 8B 9B \n\nThis translates between American and European ranges thusly:\n\nU.S.      Europe\n#1     =     B\n#2     =    HB   (most common)\n#2 1/2 =     F   (also seen as 2 4/8, 2.5, 2 5/10,   due to patent issues)\n#3     =     H\n#4     =    2H\n\nSo, as you see, the #2 pencil is used because it is a "lead" density that isn't too hard or too soft for writing in standard writing use.\n\nI am an artist and use all of these various types of pencils.  \n\nBTW, there is no actual Lead in pencils.  That is a myth.

Yeah, it shows.  At it is spelled neUrotic.\n\nAs long as you don't poke you eye out with it, it may at least make your tracing more even as the lead does not widen as it gets used.

In Rome, scribes wrote on papyrus (an early form of paper) with a thin metal rod called a stylus, which left a light but readable mark. Other early styluses were made of lead. Today we still call the core of a pencil the "lead" even though it is made from nontoxic graphite.  (Lead is toxic and leaches right through your skin, so it's not a great choice for a writing implement!)\n\nGraphite came into widespread use following the discovery of a large graphite deposit in Borrowdale, England in 1564. Graphite left a darker mark than lead, but was so soft and brittle that it required a holder. At first, sticks of graphite were wrapped in string. Later, the graphite was inserted into wooden sticks that had been hollowed-out by hand! The wood-cased pencil was born.

Pencils contain graphite, so no.

Pencil lead comes in various hardnesses, and there are many more than 3 ratings.\n\nSofter lead, makes a darker, wider mark.  Lighter lead makes a lighter, thinner mark.

Simple:  Graphite is mixed with various amounts of clay in order to create different values of pigment.  \nThe lead "hardness" ranges from HB (super soft and DARK pigment -the higher the # followed by HB, the softer the clay with a higher content of graphite) to high #'s (not followed by an HB).  The higher the # on the opposite side of the scale, the harder the clay with diminishing amounts of graphite.  \n\nA #2 pencil has just the right amount of pigment to be read by scan-tron machines and is easier to erase than darker leads when mistakes are made.

It is older than than 626 year. It comes from when archers were captured in battle they were typically very young small boys that could not wield a sword well. Most of the time they were spared but their middle finger were cut off to make them ineffective as an archer. So when some one was captured from the other side the archers would show there  fingers in devience as though saying ha ha I am still killing with this finger.

i dont know if a mole is the HEART of chemistry, but it is important for relating things from the molecular level to the measureable level\n\na pencil is not just one element, it is usually made of wood, metal, rubber, and graphite \n\nif you were asking what is the graphite (commonly called lead) is made of, it is carbon.  atoms of carbon make up molecules of graphite

Yep.  Nerves go all the way from your fingers up through your whole arm.  You probably did something funny to the nerve.  I'd see a doctor if it's not better in a couple of days.

Lead is easily absorbed through contact with the skin, ingestion or inhalation.  If I remember correctly, it binds to hemoglobin in the blood and inhibits oxygen transfer much like carbon monoxide does so it slowly smothers you to death from the inside.

It is a possibility yes, I am 35 years old, and have been a nurse for 11 years. You are at risk of many different infections/ skin infections. If your skin was peirced, you are at risk for : Hepititis, Tetnus, lead posoning, any bacterial/viral skin infections, and maybe HIV. However HIV does not die when it reaches air, especially if your blood is exposed to the virus. You really need to report this person, and get a throrough exam from a Doctor. Yu may need a Tetnus shot if you havnt had one within 5 years. Even if there is no blood. Your skin has been broken, and contamination may be in the tissue.

I was bullied until I put a girl in the hospital. That ended the problem. She threatened me, would pull pranks on me, and one day decided to put a pocket knife through my hand and stab my hand to the cafeteria table. So, I crushed her throat.... Nobody bothered me after that.
