Light and Electrons

Valence electrons are located...

• inside the nucleus

• in outer space

• on the outermost energy level in an atom

• on the energy level closest to the nucleus.

When an electron emits light

• the electron gets "excited" and "jumps out" away from the nucleus

• the electron gets "excited" and "drops back down" closer to the nucleus

• the electron "calms down" and "jumps out" away from the nucleus

• the electron "calms down" and "drops back down" closer to the nucleus

The amount of energy an electron "gives back" is

• equal to the amount of energy the electron originally received

• equal to the wavelength of the electron's orbital

• inversely proportional to the amount of energy the electron originally received

• directly proportional to the energy of the nucleus

Light and electrons are related because

• each can act as both a particle and a wave

• neither can act as both a particle and a wave

• each is a pure form of a wave only

• each are truly particles

A quantum is

• the ability to do work

• what I need

• what is required to move an electron from one energy level to a higher energy level

• what is required for an electron to orbit the nucleus

In a Bohr model of the atom, the further an electron is away from the nucleus

• the more likely it will fly off into oblivion

• the lower its energy level

• the higher its energy level

• the less likely it will be a bonding electron

To move an electron from energy level 1 to energy level 2

• requires the most amount of energy

• requires the least amount of energy

• requires no energy at all

• requires the aid of light

The further an electron is away from the nucleus, the electron requires

• less and less energy to move even further away from the nucleus

• much more energy to move even further away from the nucleus

• the input of light to move even further away from the nucleus

• the nucleus to have less neutrons than protons
