Question

What do oxygen (O) and bromine (Br) have in common? They both tend to gain electrons to gain stability. They both have seven valence electrons. They are both halogens. They are both unreactive.

Answer 1

Answer:

A

Explanation:

is the only example that they both have in common all of the rest they are absolutely the other way

one is radioactive the other one not

they are at different places ext

Answer 2

Oxygen and bromine are both nonmetals, and most nonmetals tend to gain electrons to gain stability. 

Only bromine has seven valence electrons - oxygen has six.

Only bromine is a halogen (group 7)

They are both highly reactive. Only the noble gases (group 8) are unreactive elements.
