check all that apply.
view available hint(s)

in an atom, negatively charged electrons are small particles held within a positively charged sphere.

in an atom, most of the mass and the positive charge are located in a small core within the atom called the nucleus.

in an atom, negatively charged electrons are dispersed in the space surrounding the positively charged nucleus of an atom.

in an atom, all of the positive and negative charges are randomly distributed.

Explanation:

• Rutherford's gold - foil experiment led to the nuclear model of the atom.
• In this model, most of the mass and positive charge are in a small nucleus.
• Electrons are dispersed around the nucleus.
• The “plum - pudding” model (where electrons are in a positively charged sphere with random charge distribution) was disproven by Rutherford's experiment.

Answer:

• B. In an atom, most of the mass and the positive charge are located in a small core within the atom called the nucleus.
• C. In an atom, negatively charged electrons are dispersed in the space surrounding the positively charged nucleus of an atom.
