Forms of the same elements that differ in amount of neutrons
isotopes
When alpha particles were shot at a metal foil target, most passed through without deflections, while others deflected at large angles. What did this suggest to Rutherford?
that the atoms of the metal were mostly empty space, while the nucleus consisted of most of the mass which included highly condensed positive particles (which caused the deflection).
electromagnetic spectrum
Greater wavelength = lower frequency
greater frequency = shorter wavelength
greater frequency = shorter wavelength
Electrons configuration rule that states electrons do not pair until they have to. (put one electrons in each electron domain then pair up)
Hund's rule
An experimental phenomena associated with atoms having unpaired electrons - which states such substances are attracted to magnetic fields
Paramagnetism
