Question

question
atoms contain a combination of protons, neutrons, and electrons which gives an atom its properties and makes it possible to predict their reactivity, including which ion(s) will form from that element.
of protons, neutrons, and electrons, which one(s) are found in the nucleus and which one(s) are found outside the nucleus?
answer

• protons are found in the nucleus, whereas neutrons and electrons are found outside the nucleus.
• electrons and neutrons are found in the nucleus, whereas protons are found outside the nucleus.
• protons and neutrons are found in the nucleus, whereas electrons are found outside the nucleus.
• neutrons are found in the nucleus, whereas protons and electrons are found outside the nucleus.

Explanation:

To determine which particles are in the nucleus and which are outside, we recall atomic structure: protons and neutrons are located in the nucleus (the central part of an atom), while electrons orbit outside the nucleus in electron clouds. Let's analyze each option:

• First option: States protons are in the nucleus, neutrons in the nucleus (correct), electrons outside (correct). This matches atomic structure.
• Second option: Claims electrons and neutrons are in the nucleus (incorrect, electrons are outside) and protons outside (incorrect, protons are in the nucleus).
• Third option: States protons and neutrons are in the nucleus (correct), electrons outside (correct) – same as the first option? Wait, no, re - reading: Wait, the first option says "protons are found in the nucleus, whereas neutrons and electrons are found outside the nucleus" – no, wait, no, I misread. Wait, the first option: "Protons are found in the nucleus, whereas neutrons and electrons are found outside the nucleus." No, that's wrong. Wait, no, neutrons are in the nucleus. Wait, let's re - examine:

Wait, the correct atomic structure is: Nucleus contains protons and neutrons. Electrons are outside the nucleus.

So let's re - analyze each option:

1. Protons are found in the nucleus, whereas neutrons and electrons are found outside the nucleus. → Wrong, neutrons are in the nucleus.

1. Electrons and neutrons are found in the nucleus, whereas protons are found outside the nucleus. → Wrong, protons and neutrons are in the nucleus, electrons outside.

1. Protons and neutrons are found in the nucleus, whereas electrons are found outside the nucleus. → Correct.

1. Neutrons are found in the nucleus, whereas protons and electrons are found outside the nucleus. → Wrong, protons are in the nucleus.

So the correct option is the third one (the one with "Protons and neutrons are found in the nucleus, whereas electrons are found outside the nucleus"). Wait, but in the first option as written in the image, maybe I misread. Wait, the first option in the image: "Protons are found in the nucleus, whereas neutrons and electrons are found outside the nucleus." No, that's incorrect. The third option: "Protons and neutrons are found in the nucleus, whereas electrons are found outside the nucleus." That's correct.

Answer:

The correct option is the third one (the one with the text "Protons and neutrons are found in the nucleus, whereas electrons are found outside the nucleus"). If we consider the options as labeled (assuming the first option is A, second B, third C, fourth D, fifth E): C. Protons and neutrons are found in the nucleus, whereas electrons are found outside the nucleus.
