- structure of the atom
- Protons and neutrons make up the nucleus of an atom.
- - A proton has a positive charge
- An electron has an equal negative charge
- A neutron is uncharged
- Electrons move about in the space around the nucleus.
- An uncharged atom has an equal amount of protons and ellectrons
- 1. Adding electrons to an uncharged atom makes it negative (because the atom then has more electrons than protons
- Only electrons can be transferred to or from an atom
- A charged atom is called an ion
- 2. Removing electrons from an uncharged atom makes it positive (because the atom has fewer electrons than protons)
