Question

complete the table below, using the diagram of an atom shown at right.
properties of subatomic particles
name
symbol
charge
(in multiples of e)
approximate
mass
(amu)
location
on diagram
first row: charge +1, mass 1.0, location a; second row: symbol $\ce{n^0}$; third row: symbol $\ce{e^-}$

Explanation:

To solve this, we recall the properties of subatomic particles: protons, neutrons, and electrons.

First Row (Charge +1, Mass 1.0 amu, Location A):

• Name: Proton
• Symbol: \( \boldsymbol{p^+} \) (or \( \boldsymbol{^1_1H} \), but \( p^+ \) is common)
• Charge: \( +1 \) (matches)
• Mass: \( 1.0 \) amu (matches)
• Location: A (nucleus, where protons are found).

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

• Name: Neutron
• Charge: \( 0 \) (neutrons have no charge)
• Mass: \( 1.0 \) amu (neutrons have ~1 amu mass)
• Location: A (nucleus, with protons).

Third Row (Symbol \( \boldsymbol{e^-} \)):

• Name: Electron
• Charge: \( -1 \) (electrons have a charge of \( -1e \))
• Mass: \( 0 \) amu (electrons have negligible mass, ~0 amu)
• Location: B (electron cloud/orbitals, outside the nucleus).

Filling the Table:

name	symbol	charge (in multiples of \( e \))	approximate mass (amu)	location on diagram
Neutron	\( n^0 \)	\( 0 \)	\( 1.0 \)	A
Electron	\( e^- \)	\( -1 \)	\( 0 \)	B

Final Answers (Filling Each Cell):

1. First row (name, symbol): Proton, \( \boldsymbol{p^+} \)
2. Second row (charge, mass, location): \( 0 \), \( 1.0 \), A
3. Third row (name, charge, mass, location): Electron, \( -1 \), \( 0 \), B
