Question

question 13 1 pts an atom has a charge of -3 in its orbitals. which statement must be true for this atom to have no net charge? there are two positively charged protons in the nucleus and on in an orbital there are three positively charged protons in the nucleus there are three neutral neutrons in the nucleus there are three positively charged protons outside the nucleus question 14 1 pts what did rutherfords gold - foil experiments prove the existence of? the entire atom the electrons outside the nucleus the protons the nucleus

Explanation:

For Question 13: An atom is neutral when the total positive charge (from protons) equals the total negative charge (from electrons). Given -3 charge in orbitals (from electrons), there must be 3 protons in the nucleus to balance it. Protons are in the nucleus and have a positive charge.
For Question 14: Rutherford's gold - foil experiments showed that most of the atom is empty space, but there is a small, dense, positively - charged region at the center, which is the nucleus.

Answer:

Question 13: There are three positively charged protons in the nucleus
Question 14: the nucleus
