The density of marble is between 2.6 and 2.8 grams per cm³ .
Density doesn't depend on how much mass or volume of it you have.
The density of a chip of it is the same as the density of a truckload of it.
A chemical bond is created by either the transfer or sharing of electrons. Electrons with a missing full outer shell will be the ones participating in the bonding process. Hope this helped :)
