Slide 4 - Tekstslide

What do you know about 'charge'?

Slide 5 - Woordweb

The definition
Electric charge is a physical property of matter. It is created by an imbalance in a substance’s number of protons and electrons. The matter is positively charged if it contains more protons than electrons, and it is negatively charged if it contains more electrons than protons. In both instances, charged particles will experience a force when in the presence of other charged matter.
