I am a member of the boron family and am the most abundant metal in the Earth's crust. What am I?
Owen AmbroseAluminum.
The boron family is all the elements in the column if the periodic table headed by boron. Thus boron, aluminum, gallium, indium, thalliun, element 113.
Among the elements just listed, aluminum is by far the most abundant on Earth, although some elements in other groups are even more abundant.
