Mass is measured in grams. The units for density will be g/cm³. Arrangement of atoms in different metals is similar. Individual atoms are packed very close together. Therefore, differences in density ...
The size of the atoms and their mass has a lot to do with the density of the substance Another factor is how the atoms are arranged in the substance. Polyethylene is made up only of carbon and ...
Density also depends on the material. A piece of iron with the same dimensions as a piece of aluminium will be heavier because the atoms are more closely packed. Scientists can measure how tightly ...
What makes matter stable? Why are atoms as they are? Why do different materials vary in their properties, such as electrical conductivity, density, melting temperature or light-absorption spectra?
