* Protons and Neutrons: These are the largest of the three, with almost identical masses. They are roughly 1836 times heavier than electrons.

* Electrons: These are much smaller and lighter than protons and neutrons. They have a mass that's about 1/1836th that of a proton or neutron.

To put it in perspective:

Imagine a proton or neutron as a large, heavy bowling ball. In comparison, an electron would be like a tiny marble.

Important Note:

While we talk about their "size," it's important to remember that subatomic particles aren't really solid, like balls. They behave more like fuzzy clouds of probability.
