M
When a beam of alpha particles strikes gold foil, most pass straight through, but some
are scattered; the reason for this is presence of a nucleus
atoms are mostly empty space, small dense core (nucleus), nucleus in positve

Gold Foil Experiment (Rutherford)
depends on quantity (mass, volume, moles)
how much; not what type
Give this one a try later!
extensive property
Shiny luster, high malleability, ductility, electrical and thermal conductivity.
