There are five stable isotopes of nickel: Ni-58, Ni-60, Ni-61, Ni-62, and Ni-64. Properties: The melting point of nickel is 1453Â°C, boiling point is 2732Â°C, specific gravity is 8.902 (25Â°C), with a valence of 0, 1, 2, or 3. Nickel is a silvery white metal that takes a high polish. Nickel is hard, ductile, malleable, and ferromagnetic. It is a fair conductor of heat and electricity. Nickel is a member of the iron-cobalt group of metals (transition elements). Exposure to nickel metal and soluble compounds should not exceed 1 mg/M 3 (8 hour time weighted average for a 40 hour week).
No start condition. Another common symptom of a bad or failing ignition pickup is a vehicle that does not start. If the ignition pickup fails, it will not provide the signal necessary for the vehicleâs ignition system to operate, and as a result the engine will not start or run.
Spark Plugs and Spark Plug Wires. Spark Plugs deliver electric current from the ignition system to the engine to ignite the engineâs fuel and air mixture. Bad spark plugs can cause a car hesitates, jerks, or shakes during acceleration or driving. If the spark plugs are new but you see incomplete electric spark, check on the spark plug wires.
