    An atom has 2 protons in its nucleus. Which of the following must be true for this atom to have no net charge? Question 2 options: The atom also has 2 positively charged neutrons in the nucleus.< The atom has 2 negatively charged electrons outside the nucleus. The 2 positive protons have no influence on the overall charge of the atom. The atom has 2 negatively charged electrons in the nucleus.

    Ernest Rutherford's gold-foil experiment showed which of the following? Question 3 options: the existence of subatomic particles within an atom< the existence of a dense, positively charged center in an atom the existence of electrons in an atom the existence of subatomic particles with no charge in the nucleus

    How did Rutherford discredit Thomson's plum pudding model of an atom? Question 4 options: He conducted an oil drop experiment. He didn't discredit the plum pudding model of the atom, she proved it. He conducted an experiment using gold foil and alpha particles.< He conducted experiments with a cathode-ray tube.

    2nd is wrong because they clearly says that there's no net charge, so if u have 2 protons u should have 2 electrons because protons are positive and electrons are negative.

    oh yes i agree i missed that 2 electrons are need to make it unccccccccharged

    Yea what she said ^ and electrons are found outside the nucleus, while proton and neutrons are inside the nucleus.

    For the gold foil experiment, protons,, electrons, and neutrons are already known. They found out that in a center of an atom, there is a dense heavy spots that contains proton and neutrons called the nucleus.

    his experiment showed that an atom had a dense positively charged centre.
