the atomic number of beryllium (be) is 4, and the atomic number of barium (ba) is 56. which comparison is best supported by this information?\no they are in the same group because they have similar atomic masses, but they are in different periods because they have different chemical properties.\no they are in the same group because they have similar chemical properties, but they are in different periods because they have very different atomic numbers.\no they are in the same group because their atomic numbers are each multiples of four, but they are in different periods because they have different chemical properties.\no they are in the same group because they have similar atomic masses, but they are in different periods because they have very different atomic numbers.

Answer

Answer:

They are in the same group because they have similar chemical properties, but they are in different periods because they have very different atomic numbers.

Brief Explanations:

Elements in the same group have similar chemical properties due to the same number of valence - electrons. Period number is related to the number of electron shells, and a large difference in atomic number implies a difference in the number of electron shells and thus different periods.
