Together, protons and electrons form an atom'snucleus. A proton has a positive charge that counters the electron's negative charge. When an atom has the same number of protons and electrons, it is in a neutral state. Electrons are unique from the other particles in multiple ways. They exis...
Electric charge Electric charge, also referred to simply as charge, is a basic property of some fundamental particles of matter. There are two types of charge: positive and negative. For example, an electron has a negative charge, and a positron (an anti-particle of electron) has a positive...
cloud of negatively-charged electrons. By definition, atoms are neutral entities because the positive charge of the nucleus is cancelled by the negative charge of the electron cloud. However, the gain or loss of an electron can lead to the formation of an ion, also known as a charged atom....
