The molecular geometric shape of bromate anion
In the above structure, we use (6 electrons × 3 oxygen atoms)=18 valence electrons, selected from the total remaining 20 valence electrons. (20 - 18)=2 valence electrons Now there are only two valence electrons left. Complete the octagon of the central atom, and form covalent bonds if necessary Now that we have completed the octet of the surrounding atom, we need to complete the octet of...

Chlorate and bromate are used to oxidize manganese in water samples
In 2014, NASA's Mars probe found manganese oxides in the rocks of Gael Crater and Endeavour Crater on Mars. This discovery prompted some scientists to propose that billions of years ago, there might have been more oxygen in the atmosphere of this red planet. But a new experimental study overturns this view. Scientists found that under conditions similar to Mars, manganese oxides were easily...
