Flame Tests and Spectroscopy Quiz

Sodium is commonly used as a reference standard in flame tests for its distinctive yellow flame.

Copper produces a green flame in a flame test due to the emission of specific wavelengths of light.

Strontium produces a distinctive lilac-colored flame in a flame test.

Atomic absorption spectroscopy offers higher sensitivity compared to flame tests, allowing for more precise measurements.

Rubidium produces a distinctive crimson-colored flame in a flame test.

UV-VIS in spectroscopy stands for Ultraviolet-Visible, referring to the range of electromagnetic radiation used in the technique.

Atomic spectrum refers to the unique pattern of lines in an emission spectrum associated with each element.

Spectral lines in spectroscopy are lines formed due to transitions between different energy levels in atoms.

Infrared spectroscopy covers the region of the electromagnetic spectrum associated with infrared radiation.

X-ray spectroscopy relies on the interaction of X-rays with matter to analyze the elemental composition of samples.

Flame tests and spectroscopy are based on the principle of photon absorption and emission by atoms.

Excitation is the phenomenon where atoms absorb energy and transition to higher energy states in spectroscopy.

Relaxation in spectroscopy refers to the process where an atom or molecule returns to a lower energy state by emitting a photon.

Absorption is the phenomenon where electrons are promoted to higher energy levels when atoms absorb light.

NMR spectroscopy is particularly useful for determining the structures of organic molecules by studying the nuclear magnetic resonance of atoms in a sample.
