Nickel is the 22nd most abundant element in the earth's crust and occurs in a variety of sulfide ores. Transition metals are less reactive than group 1 alkali metals towards oxygen, water and halogens like chlorine. Metals like platinum and nickel make good catalysts because they adsorb strongly enough to hold and activate the reactants, but not so strongly that the products can't break away. For example, thermodynamically a similar corrosion behavior of nickel and molybdenum is predicted in chlorine‐containing atmospheres at low oxygen partial pressures . It's only when you're exposed to the substance again that your immune system reacts and causes the skin to become red and itchy. Table 1. (a) Hydrogen is adsorbed on .
