There were several scientists that discovered that atoms contained electric charges. One of the first to look at their charges more closely was J.J. Thomson.
Atoms have NO electric charge, only ions have (+ or -)
electrons
When electrons were discovered, scientists inferred that neutral atoms contain positive charges because electrons have a negative charge and atoms were found to be neutral overall. This led to the conclusion that atoms must contain positively charged particles to balance out the negative charges of electrons, thus making atoms electrically neutral.
Correct
Electrons.
Cations.
Ions are formed when atoms have charges. Cations are species with positive charge. Anions are species with negative charge.
Atoms carry a positive charge on the proton and a negative charge on the electron, usually these cancel out.
The particle with an electric charge is called the proton. It makes up part of an atoms nucleus.
It has an equal number of protons and electrons.
