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?

a: they are in the same group because they have similar atomic masses, but they are in different periods because they have different chemical properties.
b: 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.
c: 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.
d: 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.

The answer is:

B)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.

The explanation:

The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties.

A period is a horizontal row of elements on the periodic table. For example, the elements sodium ( Na ) and magnesium ( Mg ) are both in period 3. The elements astatine ( At ) and radon ( Rn ) are both in period 6.

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

b mirrors submit a iisner? e. for which optical devices does d sometimes have a positive value? o a a and b o b. a and c o c. b and d 0 d. b and cb
