Here's a breakdown of the subatomic particles, their relative charges, and masses:

| Particle | Relative Charge | Relative Mass | Location |

|-----------------|-----------------|----------------|----------|

| Proton | +1 | 1 | Nucleus |

| Neutron | 0 | 1 | Nucleus |

| Electron | -1 | ~1/1836 | Electron cloud |

Key Points:

* Charge: Protons are positively charged, electrons are negatively charged, and neutrons have no charge (they are neutral).

* Mass: Protons and neutrons have almost identical masses, which are significantly heavier than electrons. Electrons are much smaller and lighter.

* Location: Protons and neutrons reside within the nucleus of an atom, while electrons orbit the nucleus in a cloud.

Further Details:

* Relative Mass: It's important to note that "relative mass" is a comparison to the mass of a proton, which is set to 1. Electrons are so light that they are often considered to have negligible mass in calculations.

* Atomic Number & Mass Number: The number of protons in an atom defines its atomic number and determines its element. The number of protons and neutrons together determine the atomic mass number.
