What attracts electrons to the nucleus?

Electrons are attracted to protons in the nucleus due to Coulombic attraction.

What happens to like charges and opposite charges?

Like charges repel each other, while opposite charges attract.

How does distance affect Coulombic attraction?

The further electrons and protons are from each other, the less attracted they are.

What are orbitals in relation to electrons?

Electrons are located in orbitals, which are different distances away from the nucleus.

What are valence electrons?

Valence electrons are located in the furthest energy level from the nucleus.

What occurs when electrons gain energy?

Electrons can absorb energy and move to a higher energy level, known as the excited state.

What is released when an electron drops from an excited state?

Energy is released as a photon of light when an electron returns to a lower energy state.

What is the ground state of an atom?

The ground state is the lowest energy state of an atom.

What is an excited state?

An excited state is when an atom has a higher potential energy than its ground state.

What is a line emission spectrum?

A line emission spectrum is produced when emitted light from excited atoms is separated into specific frequencies.

What is spectroscopy used for?

Spectroscopy is used to identify unknown elements by analyzing their unique emission or absorption spectra.

What is the visible light range of wavelengths?

The visible light range is between 400-750 nm.

What happens in an absorption spectrum?

An absorption spectrum shows gaps where energy has been absorbed when white light is shined on a material.

What is the relationship between wavelength and frequency?

As wavelength decreases, frequency increases, and vice versa.

How does energy relate to wavelength?

If wavelength increases, energy decreases; shorter wavelengths correspond to higher energy.

What does ROYGBIV represent?

ROYGBIV stands for the colors of the visible spectrum: Red, Orange, Yellow, Green, Blue, Indigo, Violet.

Which color of light has greater energy, purple or red?

Purple light has greater energy than red light due to its shorter wavelength.

What is the significance of gamma rays in the electromagnetic spectrum?

Gamma rays have the highest frequency and energy in the electromagnetic spectrum.

What is the effect of a current on gas atoms at low pressure?

A current can excite gas atoms, causing them to emit light when they return to the ground state.

What is a photon?

A photon is a packet of light energy emitted when an electron drops to a lower energy state.

What determines the color of emitted light?

The color of emitted light corresponds to the energy of the photon and the element involved.

What is the relationship between frequency and energy?

Higher frequency corresponds to higher energy, while lower frequency corresponds to lower energy.
