Atomic Emission Flashcard

Front

What are spectral lines?

Back

Dark or bright lines in a spectrum that correspond to specific wavelengths of light emitted or absorbed by an atom or molecule.

Front

What is the relationship between spectral lines and energy levels?

Back

Spectral lines are produced when electrons transition between different energy levels in an atom.

Front

Why is atomic emission spectroscopy important in analytical chemistry?

Back

Atomic emission spectroscopy is important in analytical chemistry because it allows for the identification and quantification of elements in a sample.

Front

What are the different types of emission spectra?

Back

Continuous spectra, line spectra, and band spectra.

Front

How can flame tests be used to identify elements?

Back

By observing the color of the flame produced when the element is heated.

Front

What is atomic emission spectroscopy?

Back

A technique that analyzes the light emitted by atoms to determine their composition.

Front

What is the principle behind flame tests?

Back

Different elements emit characteristic colors when heated in a flame.

Front

What is a continuous spectrum?

Back

A spectrum that shows all wavelengths of light without any gaps.

Front

What is a line spectrum?

Back

A spectrum that consists of discrete lines, each corresponding to a specific wavelength of light.

Front

What is a band spectrum?

Back

A spectrum that shows a series of closely spaced lines, indicating transitions between energy levels in molecules.
