None of the above is paramagnetic.
Question 41 (1 point)
I am an element on the periodic table. I am a diamagnetic non-metal. When I
combine with oxygen, it is a rare event and tends to occur only in the presence of
halogens. When I’m mixed with metals, I don’t react with them but protect them
from reactions. My size is fairly large with 36 core electrons. Which element am I?
