ʻO Nickel kahi metala paʻakikī, ductile, a me ka ferromagnetic i hoʻomaʻamaʻa maikaʻi ʻia a pale i ka corrosion. ʻO Nickel ka hui o nā mea aloha hao. ʻO ke kumu nui o ka Honua he hao a me ka nickel. ʻOi aku ka nui o ka nickel ma mua o nā pōhaku alumini silicon, no ka laʻana, ʻo ka peridotite he 1000 mau manawa ʻoi aku ka nickel ma mua o ka granite, a ʻo ka gabbro he 80 mau manawa ʻoi aku ka nickel ma mua o ka granite.

ʻOi aku ka ikaika o nā waiwai kemika, akā ʻoi aku ka paʻa ma mua o ka hao. He paʻakikī ke hoʻoheheʻe ʻia i ka ea ma ka lumi wela a ʻaʻole maʻalahi ke hana me ka nitric acid concentrated. Hiki ke ahi a hoʻopili me nā halogen ke hoʻomehana ʻia, e hoʻoheheʻe mālie i ka waika dilute. Hiki ke komo i ka nui o ke kinoea hydrogen.
