element

    In pcb an element represents any part you might install on your
    board, such as resistors, capacitors, and integrated
    circuits. Note that this also includes anything on your board that
    has its own footprint, even if it doesn't have a part associated
    with it, such as test points, registration targets, and edge
    connectors. An element has a footprint, but is more than a
    footprint - it also has a reference designator (refdes), value,
    description, and location. âFootprintâ refers to the pattern;
    âelementâ refers to the instance. For example, your layout might
    have four elements that use one footprint.

footprint

    A footprint is the pattern on a circuit board to which your parts
    are attached. This includes all copper, silk, solder mask, and
    paste information. In other EDA programs, this may be referred to
    as a âland patternâ. âFootprintâ sometimes is used to refer to a
    footprint file. âFootprintâ refers to the pattern; âelementâ
    refers to the instance. For example, your layout might have four
    elements that use one footprint.

I think this is consistent with gschem; a symbol in your schematic
specifies the footprint it needs when it becomes an element on your
board.
