Question

complete the table below, using the diagram of an atom shown at right.

properties of subatomic particles

namesymbolcharge (in multiples of e)approximate mass (amu)location on diagram
electronselectselect
+11.0a

Explanation:

Step 1: Identify the neutron

The symbol \( \ce{_n^0} \) corresponds to a neutron. Neutrons have a charge of \( 0 \) (in multiples of \( e \)), an approximate mass of \( 1.0 \) amu, and are located in the nucleus (region A in the diagram).

Step 2: Identify the electron

The electron has the symbol \( \ce{e^-} \), a charge of \( -1 \) (in multiples of \( e \)), an approximate mass of \( 0.0005 \) amu (or negligible compared to protons/neutrons), and is located in the electron cloud (regions B or the outer circles in the diagram).

Step 3: Identify the proton

The particle with a charge of \( +1 \), mass \( 1.0 \) amu, and located at A (nucleus) is the proton. Its symbol is \( \ce{p^+} \) (or sometimes just \( \ce{p} \)).

Filling the table:
namesymbolcharge (in multiples of \( e \))approximate mass (amu)location on diagram
electron\( \ce{e^-} \)\( -1 \)\( 0.0005 \) (or ~0)B (outer shells)
proton\( \ce{p^+} \)\( +1 \)\( 1.0 \)A

Answer:

namesymbolcharge (in multiples of \( e \))approximate mass (amu)location on diagram
electron\( \ce{e^-} \)\( -1 \)\( 0.0005 \)B
proton\( \ce{p^+} \)\( +1 \)\( 1.0 \)A
