What does polonium change into?
Polonium-210 decay to lead-206.
What is the graphite of a pencil?
The graphite in a pencil is a form of carbon that is bonded together in layers. It is soft and easily leaves a mark on paper when pressure is applied. Graphite is the material that makes up the "lead" in a pencil, allowing for writing or drawing.
What element does an atom of polonium change into after it emits an alpha particle?
Polonium 210-----------alpha particles-----------Lead 206 Polonium 209-----------alpha particles-----------Lead 205 Polonium 208-----------alpha particles-----------Lead 204 Polonium 214-----------alpha particles-----------Lead 210 Polonium 218-----------alpha particles-----------Lead 214 (99,98 %) Polonium 218-----------beta particles------------Astatin 218 (o,o2 %) For other isotopes see the list at: http://en.wikipedia.org/wiki/Polonium#Isotopes
How does polonium 210 become lead 206?
Polonium-210 become lead-206 after the emission of an alpha particle.
What is the percentage of lead in the lead pencil you are using?
A typical lead pencil does not actually contain lead. The "lead" in a pencil is made of graphite, which is a crystalline form of carbon. Therefore, there is 0% lead in a lead pencil.
Why does the polonium (po) become lead (pb) after a decay?
Polonium-210 lose an alpha particle and become lead-206.
Is pencil lead is Pb free?
There is no lead in pencil - Pencil is made from graphite
What is the shiny black substance in pencils called?
The shiny black substance in pencils is called graphite. It is a form of carbon that is used for writing and drawing due to its ability to leave a mark on paper. Graphite is mixed with clay to create pencil lead, with the ratio determining the hardness or softness of the pencil.
Is pencil lead solution?
Pencil lead is a compound
What makes pencils write?
it's obviouly lead Actually, it isn't lead. Scientists said it was lead, and it circled around the world. Scientists then found out it was graphite, but it was too late. In pencils, there is a slim hollow 'tube'. In that tube, there is some graphite, (Yes, graphite, not lead. People mistook it for lead.) that is stuck into the tube and makes a pencil. When you sharpen it, the pencil sharpener is a certain shape that burns the graphite and covering in a certain way that sharpens the pencil.
Is a pencil poison?
If your asking if the pencil has Lead, then the answer is that most pencils do NOT have lead in them anymore.
How can you determine if an unmarked pencil has number 2 lead?
To determine if an unmarked pencil has number 2 lead, you can perform a simple test by making a mark on a piece of paper with the pencil. Then, use your fingernail to gently rub the mark. If the mark is dark and shiny, it is likely number 2 lead, as number 2 lead creates a distinct mark that is easily smudged. Additionally, you can also check for the presence of the number "2" or "HB" on the pencil itself, as these markings are commonly used to indicate number 2 lead.
