This week in tech we learned about atoms. In every atom there are electrons, neutrons, and protons. The neutrons and protons are in the nucleus which is located in the middle of the atom. The electrons are around the nucleus. As you can see in the diagram, protons have a positive charge, electrons have a negative charge and neutrons are neutral. If the amount of protons and electrons are even then the atoms charge is zero if there are more protons, the charge is positive, if there are more electrons, then the charge is negative.
