Hydrogen, Nitrogen, Oxygen, Fluorine, Bromine, Chlorine, Iodine
400
True/False: At a negative ion, the element will lose electron(s) to form its natural gas.
FALSE! At a negative ion, the element will GAIN electron(s) to form its natural gas.
500
What are the three magnetic elements?
Iron, Nickel, and Cobalt
500
Most of the iron is turned into what?
Steel

Describe the process of electrolysis.
Part one: Stick the electrodes in Part two: Each ion will move to the oppositely charged electrode Part three: Ions will discharge at electrodes (positive ion at negative electrode, negative ion at positive electrode)
