Question

Match list 1 with list 2.

Answer 1

Electron has negative charge of $1.6\times {10}^{-19}C$.
Proton has positive charge of $1.6\times {10}^{-19}C$.
Neutron is chargeless and positron has positive charge of $1.6\times {10}^{-19}C$. Thus, positron and proton have the same charge. Electron and positron have equal charges but opposite in sign.
