Why do absorption lines differ?

Why do absorption lines differ?

The energy levels of an ionized atom are entirely different from those of the same atom when it is neutral. Ionized hydrogen, having no electron, can produce no absorption lines.

Why do elements have different absorption spectrums?

Different elements have different spectra because they have different numbers of protons, and different numbers and arrangements of electrons. The differences in spectra reflect the differences in the amount of energy that the atoms absorb or give off when their electrons move between energy levels.

Why do different elements produce different spectral lines?

When atoms are excited they emit light of certain wavelengths which correspond to different colors. The emitted light can be observed as a series of colored lines with dark spaces in between; this series of colored lines is called a line or atomic spectra. Each element produces a unique set of spectral lines.

Why do elements have a unique emission or absorption spectrum?

As each element has different energy states available to it, each element releases photons of different color when its atoms return to their lower energy states. Since each atom has many excited states (high energy levels) available to it, several colors of light can be emitted by each element.

Why do different elements produce different spectral absorption and emission lines?

Different jumps produce photons of different energies. A larger jump to a lower energy level, will produce a photon with greater energy (smaller wavelength). The atom produces light of certain wavelengths. The more atoms undergoing a particular transition, the more intense the emission line will be.

Why do absorption lines occur?

Absorption lines occur when an atom, element or molecule absorbs a photon with an energy equal to the difference between two energy levels. This causes an electron to be promoted into a higher energy level, and the atom, element or molecule is said to be in an excited state.

Why do different elements have their own characteristic color of emission spectra?

When you heat an atom, some of its electrons are “excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. The different mix of energy differences for each atom produces different colours. Each metal gives a characteristic flame emission spectrum.

Why does each element have its own unique atomic line spectrum quizlet?

Each element has its own atomic line spectrum, consisting of fine lines of individual wavelengths that are characteristic for the element. This occurs because the atom contains specific levels, and an atom can only absorb or emit radiation that corresponds to the energy between these levels.

Why do elements have more than one spectral line why aren’t there infinitely many lines?

Why do elements have more than one spectral line why aren’t there infinitely many lines? Its because, elements have electrons in orbitals. In addition there will be infinite number of empty orbitals. So when transitions occur in the atoms of an element, they absorb/release energy in the form of spectral lines.

What is likely being absorbed in an absorption line?

Absorption lines are usually seen as dark lines, or lines of reduced intensity, on a continuous spectrum. This is seen in the spectra of stars, where gas (mostly hydrogen) in the outer layers of the star absorbs some of the light from the underlying thermal blackbody spectrum.

Why do different elements produce different colors?

When you heat an atom, some of its electrons are “excited* to higher energy levels. When an electron drops from one level to a lower energy level, it emits a quantum of energy. The different mix of energy differences for each atom produces different colours.
