Please help me

Lithium will bond with oxygen to form lithium oxide. Use your knowledge of electron dot diagrams and periodic trends to explain how and why these atoms bond together.

- DESCRIBE the valence electrons of both oxygen and lithium
- Explain why the reaction between oxygen and lithium occurs
- Give the final formula for the reaction between oxygen and lithium.

Answer:

It takes two electrons to make a covalent bond, one from each bonding atom. Lewis dot structures are one way to represent how atoms form covalent bonds. A table of Lewis dot symbols of nonmetal elements that form covalent bonds is shown in Fig. 2.28 Dots are placed around the symbol of the element to represent the number of valence electrons in the element. There can be up to eight dots, for eight valence electrons. The first four electrons are placed as single electrons, then the remaining four are paired.
