Question
Rutherford tracked the motion of tiny, positively charged particles shot through a thin sheet of gold foil. Some particles travelled in a straight line and some were deflected at different angles.
Which statement best describes what Rutherford concluded from the motion of the particles?
A) Some particles travelled through empty spaces between atoms and some particles were deflected by electrons.
B) Some particles travelled through empty parts of the atom and some particles were deflected by electrons.
C) Some particles travelled through empty spaces between atoms and some particles were deflected by small areas of high-density positive charge in atoms.
D) Some particles travelled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.
Answer:
The right answer is C)
Explanation:
In the experiment described above, a piece of gold foil was hit with alpha particles, which have a positive charge. Alpha particles <em>α</em> were used because, if the nucleus was positive, then it would deflect the positive particles. The principles of physics posit that electric charges of the same orientation repel.
So most as expected some of the alpha particles went right through meaning that the gold atoms comprised mostly empty space except the areas that were with a dense population of positive charges. This area became known as the "nucleus".
Due to the presence of the positive charges in the nucleus, some particles had their paths bent at large angles others were deflected backwards.

Explanation:
Answer:
Option A
Beryllium fluoride
Explanation:
The combination of Beryllium (Be) and Fluorine (F) leads to formation of a compound called Beryllium fluoride (BeF). The name is changed to fluoride and not fluorine because the salts of fluorine are called fluoride salts. Beryllium has oxidation state of +2 being a metal with atomic number 4. Fluorine is the lightest halogen and known to be the most electronegative element due to its high affinity to attract electrons and it has atomic number 9. The combination of Be and F is a salt.
