    if we applied an electric field to a metal,
    why the direction of electrons is to be in the opposite of the direction of the electric field intensity ()?

    And, any animation or image can describe that in a better way ?

    It is simply due to the convention that segregates charges into positive and negative with the electron being negative. Look at the Lorenta force equation:

    X. The term times the E field, in the absence of a magnetic field causes the force to be directed opposite to the field for a negative charge .
