In a stable atom the amount of electrons is electron is equal to

• neutrons
• protons
• atomic mass
• neutrons + protons

Where is the neutron located?

• In the loose nucleus with the electron
• In the dense nucleus with the protons
• In the electron cloud
• The nucleus floats on orbitals

For an electron to change from ground state to an excited stated it must...

• Absorb energy
• Release energy

What is the light that you can see called?

• observatory light

• visible light

• infrared light

Emission of light from an atom occurs when an electron

• drops from a higher to a lower energy level.
•    jumps from a lower to a higher energy level.   
•    moves within its atomic orbital.
• falls into the nucleus.

Why are line emission spectra of elements called "atomic fingerprints"?

• They are all the same
• They are all unique
• They are all similar
• They all contain colored light

If an electron moves from n=4 to n=2 it ____

• absorbs energy

• releases energy
