Answer:
Plasma
Step-by-step explanation:
Plasma is a substance which is extremely hot. The heat present in plasma, a gas, is provided as energy in order to split electrons and protons apart. Therefore, ions and electrons are formed as products. Plasma is a synonym to an 'ionized gas'.
Normally, the standard states, gases, liquids and solids, wouldn't produce such an outcome, as not enough energy is present to perform the splitting pattern. This can only occur for gases at extremely high temperatures.
