Question

Based on the information in the table, which elements are most likely in the same periods of the periodic table? 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. 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 electrons, and carbon and germanium are likely together in another group because they have the same number of valence elec

Answer 1

the first one is correct

good luck!

Answer 2

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.

Step-by-step explanation:

The atomic number of barium and carbon are 5 and 6 respectively, and they both are placed on the 2nd period of the periodic table.

The atomic number of gallium and germanium are 31 and 32 respectively, and they both are placed on the 3rd period of the periodic table.

Elements in the periodic table are arranged according to increasing atomic numbers.
