Lewis Structure for Compounds

Postby Dhwani Krishnan 1G » Sun Oct 28, 2018 9:45 pm

In Class, Dr. Lavelle mentioned that you should not draw 2 cations next to each other when drawing the lewis dot structure of an ionic compound. Why is that?

I believe this is because cations are positively charges and, therefore, would repel each other if put next to each other.

This relates to electron repulsion in that two electrons of the same charge will repulse each other.

Cations lose their outermost electrons causing it to change from a neutral atom to a +positively charged atom. Two cations would repel each other since both would be +positive.

Due to electrostatic repulsion the positive cations will repel each other and this is the least likely to occur on a molecular level.

Because you two positive particles will repel to each other.

How do we know which Lewis structure is correct and whether we have to add a double bond or not?
