Explanation:
Answer:
Some particles traveled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.
Explanation:
Rutherford concluded from his experiment that there are empty spaces present in most parts of the atom while a heavy positive charge is present in the nucleus of an atom due to which the tiny positively charged particles deflects because of positive-positive charge repulsion. Most of positively charged particles passes undeflected which indicated the presence of empty spaces in the atoms. The electrons revolve around the nucleus have no effect on the deflection of positively charged particles.
Water molecules are polar, having partially positive and partially negative ends.
trust me..
idk how to explain
