number of molecules in lithium oxide
4li2O​

Sagot :

Answer:

Explanation:

Lithium is in group 1 so there's 1 outermost shell electron.

Oxygen is in group 6 so there's 6 outermost shell electron.

To react lithium with oxygen, we need 2 lithium and 1 oxygen

Each lithium transfer 1 electron to the oxygen and oxygen gain 2 electrons.

[tex]Li_{2}O\\[/tex] formed.

If there's 4 lithium oxide, 4 molecules will be there.

If you mean how many ATOMS are there, there will be 3×4=12 atoms.
