Boron and carbon are likely together in one period because they have very close atomic numbers, while gallium and
germanium are likely together in another period because they have very close atomic numbers.
O Aluminum, boron, and carbon are likely together in one period because they were first isolated in the first half of the
1800s, while gallium and germanium are likely together in another period because they were first isolated in the
second half.
Boron and carbon are likely together in one period because they each end in "-on," while aluminum, gallium, and
germanium are likely together in another period because they each end in "-ium."
Aluminum, boron, and gallium are likely together in one group because they have the same number of valence
