Atoms give line spectra because they have discrete energy levels due to quantized electron orbits. When electrons transition between these levels, they emit or absorb photons of specific wavelengths, resulting in distinct lines in the spectrum. Molecules, on the other hand, have more complex energy levels due to rotational and vibrational motion, leading to a wider range of possible energy transitions and thus a band spectrum.

What is ionic band?
An ionic band refers to the formation of a bond between two atoms where one atom gives up an electron to another atom, resulting in the formation of positive and negative ions that are attracted to each other. This type of bonding typically occurs between metals and nonmetals.
What is the relashionship between hydrogen bonds and polar attractions?
Hydrogen bonds are a specific type of polar attraction that occurs between a hydrogen atom covalently bonded to an electronegative atom and another electronegative atom. Polar attractions, in general, refer to the interactions between molecules or atoms that have uneven distribution of electron density, creating partial positive and negative charges. Hydrogen bonds are a stronger type of polar attraction compared to other dipole-dipole or van der Waals interactions.
Why coordinate covalent band is always polar?
A coordinate covalent bond is polar because one atom donates both electrons in the bond, resulting in a partial positive charge on the atom donating the electrons and a partial negative charge on the atom receiving the electrons. This charge separation creates a dipole moment, making the bond polar.
Electrons that are held most loosely in an atom are called what?
Valence electrons are the electrons that are held most loosely in an atom. These electrons are involved in chemical bonding and determine the reactivity of an element.
Why wouldn't an atom form a chemical bond?
An atom may not form a chemical bond if its outer electron shell is already stable or full, such as in the case of noble gases. These atoms have a complete valence shell, so they are typically unreactive and do not need to form bonds to achieve stability.
Identify the type of energy transition occurring in a molecule that causes a band to appear in an infrared spectrum?
The type of energy transition that causes a band to appear in an infrared spectrum is the vibration of chemical bonds within the molecule. When the molecule absorbs infrared radiation, the energy is transferred to the bonds, causing them to vibrate. The resulting changes in the dipole moment of the molecule produce distinct peaks in the infrared spectrum.
When did Spectrum - band - end?
Spectrum - band - ended in 1973.
What is a band spectrum?
A band spectrum is an absorption or emission spectrum consisting of bands of closely-spaced lines, characteristic of polyatomic molecules.
What is band spectrum?

The full range of frequencies of electromagnetic radiation is called?
That would be a spectrum or band.
Which band of the electromagnetic spectrum has the lowest frequency?
That would be sound waves, or the audio spectrum.
Which band in the electromagnetic spectrum has the highest frequency?
That's the portion of the spectrum that we call "gamma rays".
Which band of the electromagnetic spectrum has a wavelength in between infrared and uv?
The band of the electromagnetic spectrum that has a wavelength between infrared and ultraviolet is the visible light spectrum. This is the portion of the electromagnetic spectrum that is visible to the human eye and includes colors such as red, green, and blue.
What type of bonds can atoms form?
ionic, electrical attraction of separate oppositely charged ionscovalent, shared valence band electrons between 2 or more atomshydrogen, very week electrostatic bond between a hydrogen atom and some other atom in another molecule or elsewhere in the same large molecule
Why discontinuous spectrum is also called atomic or line spectrum?
Because the band is broken by colorless gaps
What is a band plan?
A band plan is a plan for distributing or allocating bandwidth within a frequency spectrum.
What do you call a band of colors arranged wavelength?
A band of colors arranged by wavelength is called a spectrum.
