Question

Categorize the following by mass and negligible mass or mass that is too little to count.

neclues
proton
electron
orbital
neutron

Answer 1

Here is the categorization based on mass:

### Significant Mass:
- **Nucleus**: The nucleus contains protons and neutrons, which have significant mass.
- **Proton**: A proton has a considerable mass (approximately 1.007 atomic mass units).
- **Neutron**: A neutron also has a significant mass (approximately 1.008 atomic mass units).

### Negligible Mass (or too little mass to count):
- **Electron**: An electron has a very small mass compared to protons and neutrons (approximately 0.000548 atomic mass units).
- **Orbital**: The term "orbital" refers to the region around the nucleus where electrons are likely to be found and does not have mass in itself.

In summary:
- **Significant Mass**: Nucleus, Proton, Neutron
- **Negligible Mass**: Electron, Orbital
