    The early Periodic table was used to classify the known elements and was used to predict the properties of the elements that had not yet been discovered.

    Which row correctly describes how this was possible?

    • Elements in the same Period displayed similar properties.

    • The arrangement of the known elements provided trends in behaviour which was used to make predictions about the unknown elements.

    • Elements in different Groups displayed similar properties.

    • The unknown elements were used to fill the gaps in the original Periodic table and were placed according to their physical properties.
