Question

what is light?

light or energy hitting an atom can...

• excite electrons up to higher energy levels in the atom.
• cause the atom to break apart.
• move the electrons into the nucleus of the atom.

Explanation:

When light or energy (in the form of photons) hits an atom, according to the principles of atomic structure and quantum mechanics, electrons in the atom can absorb this energy. If the energy of the photon matches the energy difference between two electron energy levels in the atom, the electron can be excited to a higher - energy level. Atoms do not break apart due to normal light absorption (unless in extreme cases like high - energy ionizing radiation which is not the context here). Electrons do not move into the nucleus as the nucleus is positively charged and electrons are negatively charged, and they exist in specific electron shells around the nucleus.

Answer:

excite electrons up to higher energy levels in the atom.
