Actually, what you are asking is referring to the hardness of the pencil. So both, 0.5mm and 0.7mm are the same hardness as number two pencils. The number of lead, 0.5, is a thinner lead in diameter to the 0.7.

Is a 7 mm mechanical pencil the same as a number 2 pencil?
The "number 2" designation refers to the "hardness" of the lead. The higher the number, the "harder" The "7mm" designation refers to the "thickness" of the lead. The higher the number, the thicker. They are not the same pencil.
Is 0.7 lead the same as a number two pencil?
No. 0.7 lead is just the dimension (in millimeters) The 0.7 has nothing to do with the hardness (which is what the No. 2 refers to). You can purchase 0.7 leads of various hardness that all will fit in the same mechanical pencil.
Why is pencil lead made out of Graphite?
Because pencil "lead" is not lead. Pencils haven't used lead cores since Roman times. However, lead poisoning was still possible up until the mid 20th century as the painted wooden casing often contain high concentrations of lead. Confusion about the source of the poisoning may have led (sic) people to think the core was actually made of lead, however the term "lead" does not refer to the carbon element itself, it's just a general term for a pencil's core. "Put some graphite in your pencil" just doesn't have the same ring to it as "put some lead in your pencil".

Why element makes diamonds and pencil lead?
Carbon constitutes pencil lead, charcoal and diamond. Although they appear different in appearance, they are chemically the same. Diamond is shiny and hard due to the crystalline arrangement of carbon atoms in it. Graphite or pencil lead has such an arrangement, that there are free electrons which make it a conductor of electricity. Elements like this, which are chemically the same but exhibit different physical properties are called allotropes, and the phenomenon is termed as allotropy.

Can a dog eat lead that is for a lead pencil?
I wouldn't suggest just letting your dog chew on a pencil, but I don't think it will kill them.

She was still the same as far as hyper activity and she didn't vomit or have diarrhea. But, with that, all dogs are different just as people are different and one dog might react to something differently than another.
