The smallest part of matter. It contains protons (+) neutrons (no charge) and electrons (-).
The core of the atom.
A particle in the nucleus of an atom. It has a positive charge.
A particle in the nucleus of an atom. It has no charge.
A sub atomic particle found outside of the nucleus of an atom. It has a negative charge.
The small amount of electricity that protons and electrons have. This charge positive (+) or negative (-) causes particles to attract or repel one another. (-) (+) opposites attract!!!
To push away. For example, when magnets have the same charge, you can not get them to connect together.
