Explanation:

Step1: Identify the neutron

The symbol \( \ce{_0^1n} \) (or \( \ce{n^0} \)) represents a neutron. Neutrons have a charge of \( 0 \) (in multiples of \( e \)), an approximate mass of \( 1 \) amu, and are located in the nucleus (region A in the diagram, along with protons).

Step2: Identify the electron

The electron has the symbol \( \ce{e^-} \) (or sometimes just \( \ce{e} \)). Electrons have a charge of \( -1 \) (in multiples of \( e \)), an approximate mass of \( 0 \) amu (or \( 5.486 \times 10^{-4} \) amu, but often approximated as \( 0 \) for simplicity), and are located in the electron cloud (the outer rings, region B in the diagram).

Step3: Identify the proton

The particle with a charge of \( +1 \), mass of \( 1 \) amu (wait, the dropdown shows 1.0, which is correct for proton mass), and located at A (nucleus) is the proton. The symbol for proton is \( \ce{_1^1p} \) (or \( \ce{p^+} \)).

Now, filling the table:

1. First row (neutron):

• Name: neutron
• Symbol: \( \ce{n^0} \) (or \( \ce{_0^1n} \))
• Charge: \( 0 \)
• Approximate mass: \( 1 \) amu
• Location: A (nucleus)

1. Second row (electron):

• Symbol: \( \ce{e^-} \)
• Charge: \( -1 \)
• Approximate mass: \( 0 \) amu (or \( 5.486 \times 10^{-4} \) amu, but the dropdown likely has \( 0 \) or \( 5.486 \times 10^{-4} \); if approximate, \( 0 \) is common)
• Location: B (electron cloud)

1. Third row (proton):

• Name: proton
• Symbol: \( \ce{p^+} \) (or \( \ce{_1^1p} \))
• Charge: \( +1 \) (given)
• Approximate mass: \( 1.0 \) amu (given dropdown 1.0)
• Location: A (given)

Answer:

name	symbol	charge (in multiples of e)	approximate mass (amu)	location on diagram
electron	\( \ce{e^-} \)	\( -1 \)	\( 0 \)	B
proton	\( \ce{p^+} \)	\( +1 \)	\( 1.0 \)	A
