Is bromine Paramagnetic or diamagnetic

Answer 1

Bromine is paramagnetic.

This is because the 4p subshell has a value of 4p5.

5 electrons in a p subshell (which has space for 6), means the last electron is unpaired. The unpaired electron gives it the property of paramagnetism.

Alternatively, Selenium is diamagnetic, as it has the outer subshell 4p4, meaning no electrons are unpaired.

Answer 2

I would say B2- is paramagnetic, since when you draw the molecular bond diagram you get an unpaired electron

Answer 3

C2+
