Thank you for the opportunity to help you with your question!
only has 3 electrons in total, by losing one electron, it would lose
the only electron in its outer shell of electrons, and therefore become
smaller in size. Also, electrons are negatively charged, so in losing an
electron, the lithium ion would become positive.
The Lewis Dot diagram will have 2 dots!
Let me know incase you need any further help ! Thanks :)
