The atom must be subjected to a form of energy which propels the electron(s) to a higher energy level. When the electrons return to their resting state they emit one photon of light at a certain wavelength that our eyes interpret as a color.

What is likely to happen to an atom with one valence electron?

This atom lose an electron.


What state is an atom in which an electron has moved to a higher energy level?

An atom in which an electron has moved to a higher energy level is in an excited state. This can happen when the electron absorbs energy from its surroundings, such as from light or heat. The electron will eventually return to its original energy level, releasing the absorbed energy as light.


What happen when you add an electron to an atom?

The atom becomes a negative ion.


What has to happen in order for an atom to lose an electron?

For an atom to lose an electron, it must undergo the process of ionization where it gains enough energy to overcome the attraction of the nucleus and the electron is released. This can happen through various means such as exposure to high-energy radiation or collisions with other particles.


What happen when a atom that has lost an electron comes in contact with an atom that has gained an electron?

-Apex: They form an Ionic Compound.


How does an electron must move in order to release a photon of light?

An electron must move from a higher energy level to a lower energy level within an atom in order to release a photon of light. This process, known as electron transition, results in the emission of light energy in the form of a photon.

What happen when a sodium atom that has lost an electron comes near a chlorine atom that has gained an electron?

Sodium chloride is formed by an ionic bond.


What happens when an electron collides with an atom?

When an electron collides with an atom, it can transfer energy to the atom, causing the atom to become excited or ionized. This can lead to the atom emitting light or undergoing chemical reactions.
