Question

1. rutherford proposed that atoms have positive nuclei.

which statement correctly describes the nucleus of an atom?
the charge on the nucleus determines the charge of the atom.
most of the mass of an atom is located in the nucleus.
most of the volume of an atom is taken up by the nucleus.

Explanation:

• The charge of an atom is determined by the balance between protons (positive charge in nucleus) and electrons (negative charge outside nucleus), not just the nucleus charge.
• In Rutherford's model, most of the atom's mass is in the nucleus (protons and neutrons have significant mass compared to electrons).
• The nucleus is very small in volume compared to the whole atom (electrons occupy most of the volume).

Answer:

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