There is no lead in pencil - Pencil is made from graphite
Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
The chemical name is lead. The symbol for the element lead is Pb, for plumbum, which comes from Latin for lead.
Symbol: Pb make sure you so capital P and lower case b
the element symbol for lead would be Pb.
Lead is one of the elements. Therefore, if you have pure lead, its makeup is lead. Lead has 82 protons, 105 neutrons, and 82 electrons in its most common isomer.
pencil is hetrogenous because it consists of wood and lead, but if they tell that lead, that will be an element, which symbol is pb.
Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
The chemical symbol for lead (element) is Pb. THe formula is Pb2 Pencil lead however, is a mix of graphite and clay.
Pencil "lead" is not really lead, the metal - Pb. Pencils are made with graphite which is a mineral, an insulator.
Yes, depending on how thick of lead you got in your pencil will very, if you have 2 pb than it can weigh up to 10 grams
Graphite is the material that pencil "lead" is made from, but lead in it's strictest sense refers to the element itself (Pb on the periodic table).
No, the lattice structure of diamonds is different from the lattice structure of lead or graphite, although both are formed from carbon. (The answer assumes that you are referring to pencil lead and not the chemical lead: Pb.)
The homophone of "led" is "lead." "Led" is the past tense of the verb "lead," while "lead" is a chemical element with the symbol Pb.
False, Pb (lead) is an electrolyte and can pass electricity VERY efficiently, but unfortunately pencil "lead" is actually graphite, which is a derivative of stone, and will not effectively pass an electric current.
If you're talking about pencil lead, it's made up of layers and layers of carbon. For example, when you write with pencil, the lines that you make on paper are just layers of carbon that had come off your pencil lead.
Pb , derived from Plumbum.
The chemical name is lead. The symbol for the element lead is Pb, for plumbum, which comes from Latin for lead.
