Here's a summary of electrons, protons, and neutrons:

• An electron is a subatomic particle with a negative elementary charge ($-1.602 \times 10^{-19} \text{ C}$). It has a very small mass, approximately $9.109 \times 10^{-31} \text{ kg}$, and orbits the atomic nucleus in electron shells.

• A proton is a subatomic particle found in the atomic nucleus. It carries a positive elementary charge ($+1.602 \times 10^{-19} \text{ C}$) and has a mass of approximately $1.672 \times 10^{-27} \text{ kg}$, which is about 1836 times greater than an electron's mass. The number of protons defines the atomic number of an element.

• A neutron is a subatomic particle also located in the atomic nucleus. It has no net electric charge (it is neutral) and a mass very similar to that of a proton, approximately $1.674 \times 10^{-27} \text{ kg}$. Neutrons contribute to the atomic mass and help stabilize the nucleus.
