What causes atoms to have magnetic properties

The motion of electric charges induces magnetism. There are electrons in every atom, particles that bear electric charges. The electrons surround the nucleus, or heart, of an atom, like spinning tops. Their motion induces an electrical current which causes every electron to behave like a microscopic magnet.

Explanation:

species of atoms possess a magnetic moment—that is, that such an atom itself is an elementary electromagnet produced by the motion of electrons about its nucleus and by the spin of its electrons on their own axes.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
