Atomic Emission Spectra

Front

What is the ground state of an electron?

Back

The ground state is the lowest energy state of an electron in an atom, where it is closest to the nucleus.

Front

What happens to an electron when it absorbs energy?

Back

When an electron absorbs energy, it can move from a lower energy level (ground state) to a higher energy level (excited state).

Front

What are spectral lines?

Back

Spectral lines are distinct lines in a spectrum that correspond to specific wavelengths of light emitted or absorbed by electrons transitioning between energy levels.

Front

How are spectral lines related to energy levels in an atom?

Back

Spectral lines are produced when electrons transition between different energy levels in an atom, emitting or absorbing photons of specific energies.

Front

What is the purpose of flame tests in atomic emission spectroscopy?

Back

Flame tests are used to identify the presence of specific elements in a sample based on the characteristic color of the flame produced when the sample is heated.

Front

What is an excited state of an electron?

Back

An excited state is a higher energy state of an electron, where it has absorbed energy and moved to a higher energy level.

Front

What is the relationship between energy absorption and electron transitions?

Back

Electrons must absorb energy to transition from a lower energy level to a higher energy level.

Front

What elements were identified in the unknown sample?

Back

The unknown sample contained elements B and C.

Front

What is the significance of the color of the flame in a flame test?

Back

The color of the flame indicates the presence of specific elements, as different elements emit characteristic colors when heated.

Front

What is atomic emission spectroscopy?

Back

Atomic emission spectroscopy is a technique used to analyze the light emitted by atoms when they are energized, allowing for the identification of elements.
