Chem - wave mechanics and orbitals

photons of light exhibit behaviour of both electromagnetic ____ and ___

Waves and particles

Light bends though a prism to split into coloured components, yet light travels in ____ lines and is reflected lie a particle

Straight lines

Louis de broglie

• Proposed the idea that particles (an electron) could also exhibit wave properties if its mass was extremely small

• Developed the idea of particles have a wavelength

Erwin schrodinger

Applied this concept to electrons in atoms, and developed mathematics called “wave mechanics”

Based on the idea that if an electron has a wavelength, then quantized energies are only possible for a ______ _______ multiple of the electrons wavelength

whole number

The electrons forms a _____ standing wave pattern around the nucleus

circular standing wave

Erwin mathematical explanation included all ____ quantum numbers and produced the energies of all orbitals

4

Heisenberg’s Uncertainty Principle

it is impossible to simultaneously know both the position and speed of an electron

the __________ is a mathematical or graphical representation of the probability or chance of finding an electron in a given space

electron probability density

orbitals or _______, are regions in space where electrons are likely to be found

electron clouds

each type of orbital has a different _____ (described by Schrodinger mathematical equation)

shape
