A helpful chart

Here is how i drew it: https://snipboard.io/WehZdQ.jpg And it has 14 valence electrons But idk how many bonds are formed

Tranquility · Answer

For it to be stable and have a full octet, it would only form one bond|dw:1636781513618:dw|

Bromine is a halogen with 7 valence electrons. It needs only one more to be stable and have a noble gas configuration. Thus the two bromines share an electron forming a covalent bond to make it stable.

If you take one bromine as the central atom, how many other atoms is it bonded to?

Br - Br

There's two atoms here. How many atoms is the left bromine bonded to?

kekeman · Answer

So there are 4 total domains, 1 bonded atom, and 3 lone pairs?

Tranquility · Answer

Yes
