Question

properties of subatomic particles

name	symbol	charge (in multiples of e)	approximate mass (amu)	location on diagram
☐	☐	+1	1.0 ▾	a ▾
☐	$\ce{p^+}$	☐	select ▾	select ▾

Explanation:

To solve the table about subatomic particles, we use knowledge of protons, neutrons, and electrons:

First Row (Symbol \( \boldsymbol{\ce{n^0}} \)):

• Name: Neutron (neutral subatomic particle in the nucleus).
• Charge: \( 0 \) (neutrons have no charge).
• Approximate Mass: \( 1.0 \) amu (same as protons, since neutrons and protons have nearly identical mass).
• Location on Diagram: \( A \) (nucleus, where protons and neutrons are found).

Second Row (Charge \( \boldsymbol{+1} \), Mass \( \boldsymbol{1.0} \) amu, Location \( \boldsymbol{A} \)):

• Name: Proton (positively charged subatomic particle in the nucleus).
• Symbol: \( \ce{p^+} \) (matches the third row’s symbol, confirming this is proton).

Third Row (Symbol \( \boldsymbol{\ce{p^+}} \)):

• Name: Proton (positively charged particle in the nucleus).
• Charge: \( +1 \) (protons have a positive charge of \( +1e \)).
• Approximate Mass: \( 1.0 \) amu (mass of a proton is ~1 amu).
• Location on Diagram: \( A \) (nucleus, where protons are located).

Filling the Table (assuming the middle row is Electron, but correcting based on symbols):

Wait, the middle row’s symbol is missing, but the third row has \( \ce{p^+} \) (proton). Let’s re-express:

Name	Symbol	Charge (multiples of \( e \))	Approximate Mass (amu)	Location on Diagram
Proton	\( \ce{p^+} \)	\( +1 \)	\( 1.0 \)	\( A \)

| (Wait, the middle row likely has \( \ce{e^-} \) for Electron, but the given table has a row with \( \ce{p^+} \) and a row with \( \ce{n^0} \). Let’s align:

For \( \ce{n^0} \) (neutron):

• Name: Neutron
• Charge: \( 0 \)
• Mass: \( 1.0 \) amu
• Location: \( A \) (nucleus)

For \( \ce{p^+} \) (proton):

• Name: Proton
• Charge: \( +1 \)
• Mass: \( 1.0 \) amu
• Location: \( A \) (nucleus)

The middle row (with charge \( +1 \), mass \( 1.0 \), location \( A \)) is also Proton, so the table is consistent for protons and neutrons.

Final Table (Key Entries):

• First row ( \( \ce{n^0} \)): Name = Neutron, Charge = \( 0 \), Mass = \( 1.0 \), Location = \( A \).
• Middle row: Name = Proton, Symbol = \( \ce{p^+} \), Charge = \( +1 \), Mass = \( 1.0 \), Location = \( A \).
• Third row ( \( \ce{p^+} \)): Name = Proton, Charge = \( +1 \), Mass = \( 1.0 \), Location = \( A \).

(Note: If there’s a row for electrons, it would have symbol \( \ce{e^-} \), charge \( -1 \), mass \( \approx 0 \) amu, and location \( B \) (electron cloud). But the given table focuses on \( \ce{n^0} \) and \( \ce{p^+} \) here.)
