What is the attractive force between like molecules involved in capillary action?
Electron
A subatomic particle with a negative charge, found in the electron clouds surrounding the nucleus of an atom.
Line Spectra
Line spectra are the emission or absorption of light at specific wavelengths by atoms or molecules transitioning between energy levels, resulting in distinct lines characteristic of the substance.
Quantized Energy Levels
The concept in quantum mechanics that energy levels in atoms and molecules are discrete, not continuous.
Spectral Emissions
The set of wavelengths or frequencies emitted by a substance or object, often used to identify its composition.
