What happens to electrons in a metal when an electric current occurs in it? What happens to ions in liquids and gases when an electric current occurs in them?

Electrons in metals begin to move in an orderly direction. Ions in liquids and gases behave similarly, negative ions move to the positive electrode of the current source, and positive ions move to the negative electrode of the current source.
