Palladium consists of several isotopes. The density of a naturally occurring sample, which is a mixture of isotopes is 12.02 g/cm3. I have no reference material for individual isotopes. There is a book called the CRC Handbook of Chemistry and Physics which may have this information.
Atomic number of palladium is 46. So there are 46 protons and 46 electrons. Mass number is 106. Mass number = number of protons + number of neutrons. So number of neutrons = 106 - 46 = 60
Palladium's mass number is 106
11995 kgm3
60 neutrons for the isotope Pd-106
Pd (palladium) is the 46th element so has 46 protons. This means that (uncharged) it has 46 electrons. The atomic mass for Pd rounds to 106. Now atomic mass = protons + neutrons, so neutrons = atomic mass - protons. Therefore, neutrons(Pd) = 106 - 46 = 60. Meaning Pd has 60 neutrons.
Palladium is a non metal element. Atomic mass of it is 106.
The population density of Lodosa is 106 people per square kilometer.
The element platinum (Pt) has 78 protons in the atomic nucleus.
The population density of Horný Bar is 106 people per square kilometer.
Łuszczów Pierwszy's population density is 106 people per square kilometer.
The best way to find out if your jewelry is made of palladium is to test its weight. Palladium is a rarer metal found in jewelry. However, one can often tell if jewelry is made of palladium because it weighs less than platinum.
Pau dos Ferros's population density is 106 people per square kilometer.
