True. Elements emit light or color when they are excited, typically by absorbing energy. This can occur through various processes such as heating, electrical discharge, or other forms of energy input. When the electrons in the atoms of an element gain energy, they can jump to higher energy levels. When they fall back to their original energy levels, they release energy in the form of light, which can be observed as color. This phenomenon is observed in processes like atomic emission spectra and is the basis for applications such as neon lights and fireworks.
