isotopes of palladium exist, 102 Pd, 105 Pd, 106 Pd, 108 Pd, and 110 Pd. Palladium (pronounced \pe-‘l&228;-dē-em\) is a rare and lustrous silvery-white metal that was discovered in 1803 by William Hyde Wollaston, who named it palladium after the asteroid Pallas, which in turn, was named for the Greek Goddess of Wisdom. Bulk palladium is paramagnetic, but it is theoretically predicted that palladium could be turned into a magnetic state if some conditions were fulfilled concerning structure and/or particle size and shape. Palladium is also an excellent hydrogenation and dehydrogenation catalyst and is available in many organometallic forms for this purpose. The application of PdNPs in the biomedical field is yet to be adequately investigated, although the green-synthesized palladium nanoparticles possess remarkable antioxidant and antimicrobial activities.
