SolutionsAtoms and their Properties
1. The particles of the atom
State the charge of each particle of the atom and where it is found.
| Particle | Charge | Where it is |
|---|---|---|
| Proton | Positive | Nucleus |
| Neutron | None | Nucleus |
| Electron | Negative | Periphery (atomic orbitals) |
2. Sizes
Arrange from smallest to largest: a hydrogen atom, its nucleus and an electron.
Electron < nucleus < atom. The nucleus is about 100,000 times smaller than the atom, and the electron at least 1,000 times smaller than the nucleus.
