Question

while looking at bromine (br) on the periodic table, a student needs to find another element with very similar chemical properties but with a different atomic mass. which best describes the students options? there are two possible elements, and they are directly to the left and right of bromine. there are two possible elements, and they are directly above and below bromine. there are many possible elements, and they are all in the same vertical column as bromine. there are many possible elements, and they are all in the same horizontal row as bromine.

Explanation:

Elements in the same group (vertical column) of the periodic table have similar chemical properties. Bromine is in group 17. There are multiple elements in group 17 (such as fluorine, chlorine, iodine, astatine, tennessine), all with different atomic masses. Elements in the same row (period) have different chemical properties. Elements to the left and right (same period) have different properties.

Answer:

There are many possible elements, and they are all in the same vertical column as bromine.
