Question

classify the following statements as consistent or inconsistent with rutherfords nuclear theory as it was originally stated. a phosphorus atom has 15 protons in its nucleus and 150 electrons outside of its nucleus. since electrons are smaller than protons, and since a hydrogen atom contains only one proton and one electron, it must follow that the volume of a hydrogen atom is mostly due to the proton. a nitrogen atom has seven protons in its nucleus and seven electrons outside of its nucleus. the majority of the mass of a fluorine atom is due to its nine electrons.

Explanation:

To solve this, we use Rutherford’s nuclear theory:

1. Most of an atom’s mass and positive charge are in the nucleus.
2. Electrons are outside the nucleus, with negligible mass.
3. Atoms are neutral (protons = electrons).

Analyzing Each Statement:

• “A phosphorus atom has 15 protons in its nucleus and 150 electrons outside of its nucleus.”

Rutherford’s theory states atoms are neutral (protons = electrons). Here, protons (15) ≠ electrons (150). Inconsistent.

• “Since electrons are smaller than protons, and since a hydrogen atom contains only one proton and one electron, it must follow that the volume of a hydrogen atom is mostly due to the proton.”

Rutherford’s theory says the nucleus (proton) is tiny, and most of the atom’s volume is empty space (electrons move in this space). So the volume is not due to the proton. Inconsistent.

• “A nitrogen atom has seven protons in its nucleus and seven electrons outside of its nucleus.”

Nitrogen is neutral (protons = electrons = 7), and protons are in the nucleus, electrons outside. This matches Rutherford’s theory. Consistent.

• “The majority of the mass of a fluorine atom is due to its nine electrons.”

Rutherford’s theory states electrons have negligible mass; most mass is in the nucleus (protons/neutrons). Electrons do not contribute most mass. Inconsistent.

Final Classification:

• Consistent: A nitrogen atom has seven protons in its nucleus and seven electrons outside of its nucleus.
• Inconsistent: A phosphorus atom has 15 protons in its nucleus and 150 electrons outside of its nucleus; Since electrons are smaller than protons… the volume of a hydrogen atom is mostly due to the proton; The majority of the mass of a fluorine atom is due to its nine electrons.

Consistent:

A nitrogen atom has seven protons in its nucleus and seven electrons outside of its nucleus.

Inconsistent:

A phosphorus atom has 15 protons in its nucleus and 150 electrons outside of its nucleus.
Since electrons are smaller than protons, and since a hydrogen atom contains only one proton and one electron, it must follow that the volume of a hydrogen atom is mostly due to the proton.
The majority of the mass of a fluorine atom is due to its nine electrons.
