No, this number is the result of the natural mixture of Cl-35 and Cl-37, which produces the observed <span>value.
</span><span>The mass of Cl on the periodic table is 35.45 atomic mass units. This is an average mass of the isotopes (different Cl atoms in nature). Most Cl atoms in nature have a relative mass of about 35 atomic mass units. Most of the remaining Cl isotopes have a relative mass of 37 atomic mass units. </span>
Density is how much matter is packed into a certain substance. So it's a measure of how tightly packed particles are. If particles are tightly packed, they will be more dense and if they're loosely packed they will be less dense. Normally, something solid will be more dense than something liquid. So density is how much matter there is a certain amount of space or volume.
Fusion or melting is the phase change from solid to liquid.
Jupiter, Saturn are two planets that have solid cores.
