Where can i find drawing of electron dot stuctures for compounds like BR2 and HCN
HCN is at the link below.

I couldn't find one for Br2 on line but here is how it will look.

That is 14 electrons around Br2. I hope this comes out right. If not I will try to adjust the spacing to make it look better.

To find electron dot structures for compounds like Br2 (bromine) and HCN (hydrogen cyanide), you can follow these steps:
1. Start with the Lewis symbol for each element.
- For Br2, the Lewis symbol for bromine (Br) is represented as ":Br:".
- For HCN, the Lewis symbols for hydrogen (H) and carbon (C) are represented as ":H:" and ":C:", respectively.
2. Determine the number of valence electrons for each element.
- Bromine (Br) has 7 valence electrons, so for Br2, there are a total of 14 valence electrons.
- Hydrogen (H) has 1 valence electron, and carbon (C) has 4 valence electrons. Hydrogen cyanide (HCN) has a total of 10 valence electrons.
3. Distribute the valence electrons around the symbols.
- For Br2, you want to draw a double bond between the two bromine atoms. This means each bromine shares one electron with the other. The final Lewis structure will look like this:
.. ..
:Br:Br:
.. ..
- For HCN, hydrogen (H) forms a single bond with carbon (C), and carbon forms a triple bond with nitrogen (N). The final Lewis structure will look like this:
.. ..
:H:C:N:

If you couldn't find an electron dot structure for Br2, you can create it by following the above steps and using "dots" or "x" to represent electrons. Note that the arrangement of the dots may vary depending on how the molecule is drawn.
Remember to always check the valence electrons and follow the octet rule (except for hydrogen) when drawing Lewis dot structures.
