What did ernest rutherford’s gold foil experiment demonstrate about atoms? their positive charge is located in a small region that is called the nucleus. their negative charge is located in small particles that are called electrons. their nucleus makes up the majority of the volume of the atom.
their electrons are floating in a sea of positive charges.

Okay so Rutherford's gold foil experiment gave three conclusions:
-the atom is mostly empty space
-in it is a small, dense nucleus
-the nucleus is positively charged.

S you don't want the one about the negitivity being in the electrons because that wasn't a conclusion of the experiment. You'd want to pick "Their positive charge is located in a small region that is callled the nucleus"

Thermohaline circulation and gyres

Cause its being chemically applied?
