Question

rutherford proposed that atoms have positive nuclei. which statement correctly describes the nucleus of an atom? the nucleus contains the protons and electrons. most of the volume of an atom is taken up by the nucleus. most of the mass of an atom is located in the nucleus. the charge on the nucleus determines the charge of the atom.

Answer 1

Most of the mass of an atom is located in the nucleus.

Answer 2

The statement that correctly describes the nucleus of the atom is that most of the mass of an atom is located in the nucleus. The nucleus contains neutrons and protons. Rutherford reasoned that all of the atom's positively charged particles were contained in the nucleus and the negatively charged particles were scattered outside the nucleus. Both neutrons and protons are given a mass of one atomic mass unit or amu. Electrons have a mass many times smaller than 1 amu.
