Electron Path

Orbits and orbitals are the same.

Orbitals are specific shapes where electrons live in, while orbits are paths around the nucleus.

Orbits are found in the nucleus, while orbitals are found outside the nucleus.

Orbits are specific shapes where electrons live in, while orbitals are paths around the nucleus.

Electrons have a predictable path around the nucleus.

Electrons orbit the nucleus like planets orbit a star.

Electrons have an unpredictable path and are found in the electron cloud.

Electrons are stationary around the nucleus.
