not positive but jj thomson
The answer is electrons.

The small, negatively-charged particle in an atom is an electron. However, this is not in the nucleus. The small negative particles in the nucleus are down quarks, which are smaller than protons and electrons. Strange quarks and bottom quarks are also negative, but are not found in the nucleus.
Generally, the theoretical first is given to Richard Laming of England in 1851. More theoretical work and the term "electron" came from G. Johnstone Stoney between 1874 and 1891. The actual "discovery" is given to J. J. Thomson in 1897.
they are small very light particles in the shell of atoms .they are negatively charged and are mainly resposible for conduction of electricity in materials
Current Carries Negatively charged electrons.
There are many subatomic particles with negative charge, but the first negatively charged particle that anyone learns about is the electron. It is only invisible in the sense that humans can not see it because it is so small. It is a perfectly normal subatomic particle and certainly the most common negatively charged particle in the universe.
Electrons, small negatively charged particles with very little mass compared to that of the nucleus.
Electrons are extremely small particles that circle the nucleus of an atom in an orbital. Electrons are negatively charged and balance the positive charge of the proton, in the nucleus. Valence electrons are either added or eliminated from an element during chemical reactions. Valence electrons are important in bonding, and the sharing of those electrons.
