Electrons and Light

What is an orbital?

Space in an atom where an electron is likely to be

What are orbital diagrams?

sublevels shown in boxes

What is electron configuration?

Condesned representation

Aufbau Principle

Lowest to highest level

Hund’s Rule

Fill each sublevel singly before pairing up

Pauli Exclusion Principle

Each orbital can only hold two electrons, and they must have opposite spins.

Noble Gas Configuration

List the noble gas before the element in brackets, then continue with the electron configuration

What is light?

A form of energy that acts as both a wave and a particle

What are characteristics of waves with shorter wavelengths?

More energy, higher frequency

What are characteritics of longer wavelengths?

Less energy, lower frequency

How is color a thing?

Within the visible light spectrum, the different colors have different wavelengths, therfore have different energies, frequencies, and speeds.

Diffraction Grating

Tiny film with grooves that bends light into different colors.

Line emission spectrum

Lines created by an element’s light emission going through diffraction grating, can indentify an elemtent or the element in a compound/molecule

How is light created?

Electrons have specific energy levels and can jump between them. When an electron jumps down, energy is released in the form of light

How do light energies differ?

The closer shells have less energy, and the farther ones have more. Dropping multiple levels at once loses more energy. Depending on which levels the electrons jumps to/from, the energies cna be different.
