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 student’s 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.

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

elctricity and magnet is conversion to it

3. dark matter

empty space could also be a simple vacuum
