CHEM 333 Its Not Rocket Science:
Chemistry- Unit 3: Electrons Questions and
Answers 2026 Latest Update
Electron Ans: a negatively charged subatomic particle
electromagnetic radiation Ans: a form of energy that exhibits wavelike
behavior as it travels through space
Wavelength Ans: The distance between two corresponding parts of a wave
Frequency Ans: the number of complete wavelengths that pass a point in a
given time
emission spectrum Ans: the spectrum of light released from excited atoms
of an element
Heisenberg uncertainty principle Ans: states that it is impossible to
determine simultaneously both the position and velocity of an electron or
any other particle
valence electrons Ans: The electrons in the outermost shell of an atom;
these are the electrons involved in forming bonds.
octet rule Ans: States that atoms lose, gain or share electrons in order to
acquire a full set of eight valence electrons
Ions Ans: positively and negatively charged atoms
Lewis structure Ans: A model that uses electron-dot structures to show how
electrons are arranged in molecules. Pairs of dots or lines represent bonding
pairs.
