If water does break down by electrolysis to form new substances, what might be formed?

Hydrogen and Oxygen molecules would be a result of that

The answer should be vaporization 

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
