Semester Review 3 Electrons/Periodic Table

Includes all forms of electromagnetic radiation; the types of radiation differ in their frequencies and wavelengths.

• electromagnetic spectrum
• electromagnetic radiation
• photon
• photoelectric effect

The number of waves that pass a given point per second.

• frequency
• wavelength
• amplitude
• Planck's constant

The lowest allowable energy state of electrons.

• principle energy level
• atomic orbital
• energy sublevel
• ground state

what are the rings the electron orbit in called 

• orbital 
• energy level 
• engrgy ring 
• electron  circle 

electrons can gain a quantum of energy and when they do they become excited which is a lower energy level

• true
• false

High energy is the longest wavelength

• True

• False

Visible light is in the middle of the spectrum?

• True 
• False

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.
