An atom gets over all positive charge by ____ _______
Rasek [7]
<h2>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.
