QuestionNeutral atoms of isotopes of an element have the same (A) protons, (B) neutrons, (C) electrons, (D) mass numbers, (E) masses.
Studdy Solution
STEP 1
Assumptions1. We are dealing with neutral atoms, which means the number of protons equals the number of electrons.
. Isotopes of a given element have the same number of protons, but different numbers of neutrons.
3. The mass number of an isotope is the sum of its number of protons and neutrons.
4. The mass of an isotope is determined by its mass number and the binding energy of the nucleus.
STEP 2
From the first assumption, we know that neutral atoms of all isotopes of a given element have the same number of protons and electrons. This eliminates option (B), (), and (), which refer to neutrons, mass numbers, and masses, respectively.
STEP 3
From the second assumption, we know that isotopes of a given element have different numbers of neutrons. This eliminates option (A), which states that the number of protons and neutrons are the same.
STEP 4
The only remaining option is (C), which states that neutral atoms of all isotopes of a given element have the same number of electrons. This aligns with our first assumption, so (C) is the correct answer.
Neutral atoms of all isotopes of a given element have the same number of electrons.
