Answer:
Rb2O
Explanation:
Rb is a 1+ element and Oxygen is a 2- element. To have a neutral overall charge you must change the molar ratio to have 2 (1+ elements) and 1 (2- element). Together add to 2+(-2)=0. So the overall product is neutral.

A conductor allows current to flow easily through it. An Insulator doesn't allow current to flow through it. Electric charge exists on the surface of conductors. Electric charges are absent in insulators.
