Atoomikada1

Nikkel waa bir adag, ductile, iyo ferromagnetic bir aad loo sifeeyey oo u adkaysata daxalka. Nikelku waxa uu ka tirsan yahay kooxda curiyayaasha birta jecel. Xudunta dhulku waxay inta badan ka kooban tahay birta iyo curiyayaasha nikkel. Dhagaxyada magnesium-ka birta ee qolofta ku jirta waxa ku jira nikkel ka badan silikoon aluminium dhagaxa ah, tusaale ahaan, peridotite waxa ku jira 1000 jeer nikkel ka badan granite, gabbrona waxa ku jira 80 jeer ka badan nikkel marka loo eego granite.

hantida kiimikada

Waxyaabaha kiimikaadku aad ayay uga firfircoon yihiin, laakiin way ka xasilloon yihiin birta. Way adag tahay in hawada lagu oksijiso heerkulka qolka oo aan si fudud looga falcelin nitric acid. Siligga nikkelka ah waa guban kara wuxuuna ka falceliyaa halogens marka la kululeeyo, si tartiib ah ugu milma aashitada. Wuxuu nuugi karaa xaddi badan oo gaasta hydrogen ah.
