They both have two electron shells. Period indicates number of shells.

The lithium and oxygen being in the same period will have two electrons shells.

  • In a periodic table, there are 7 periods and 18 groups.
  • The vertical columns are known as groups.
  • The horizontal rows are known as periods. The period number tells us about the number of electron shells.
  • Elements in the same period have the same principal quantum number that is the total number of electron shells are the same.
  • Elements in the same group have the same number of valence electrons in their valence shell.

So, from this, we can conclude that lithium and oxygen being in the same period will have two electrons shells.
