Luke Bright Lab 7684 1. Define excitation and emission as they pertain to electrons. Excitation occurs when an electron jumps from a lower energy level to a higher energy level by absorbing energy from light or electricity. Emission occurs when an electron relaxes from a higher energy level to a lower energy level, and it results in the release of energy as a photon.
Why does a sodium street lamp give off a yellow color whereas ... - BRAINLY
The color of the light depends on the element to which it interacts. On interacting with energy, the electrons goes to the higher excitation state and when electron drops to lower state which is more stable, the energy is re-emitted as light.
You are cooking spaghetti in water you have salted with NaCl ... - Quora
Answer (1 of 2): When natural gas burns completely, producing only carbon dioxide and water, it gives off a uniform blue color. When it burns incompletely, producing carbon monoxide and carbon soot in addition to water and carbon dioxide, it produces a red/yellow/orange color. Spilling water on ...

How does striking an electron with a photon affect its motion?
by striking it with a photon, the electron has such a small mass that striking it with a photon affects its motion in a way that cannot be predicted accurately; the very act of measuring the position of the electron changes its velocity , making its velocity uncertain
What happens when light shines on metal?
electrons are ejected when light shines on metal, not just any frequency of light will cause the photoelectric effect
Why are cations and anions positively charged?
Cations are ions that are positively charged because it lost electron and anions are ions that are negatively charged because they gained electrons. The attraction force between the cation and anion forms an ionic bond because opposite charges attract.
What makes a gas glow?
An electric current passing through the gas in each glass tube makes the gas glow with its own characteristic color
How do ionic bonds form?
an ionic bond forms from the attraction between positive and negative ions (cations are attracted to anions)
Do atoms lose electrons?
atoms will gain or lose enough electrons to make them isoelectric (having the same same number of electrons) with a noble gas
Can we pinpoint where an electron is?
model of electrons within an atom that says we cannot pinpoint where an electron is, but we can get the probability of where the electron is
