Answer:</h2>
Nucleus.
<h2>
Explanation:</h2>
- In an atom the nucleus has an overall positive charge as it contains the protons.
- Every atom has no overall charge (neutral). While atoms do contain charged particles, they have the same number of positive protons as negative electrons( for example a sodium atom has 11 electrons which are of negative charge and 11 protons which are of positive charge).
- These opposite charges cancel each other out making the atom neutral.
Result: Nucleus is the overall positive charge of an atom.
The formula unit for Li and O is —————-> Li2O
