Solution
Solution Steps
Step 1: Identify the subatomic particles
The diagram shows an atom with a nucleus (A) and electrons (B) in orbitals.
The subatomic particles are electrons, protons, and neutrons.
Step 2: Fill in the properties for electrons
Name: Electron
Symbol: e⁻
Charge: -1
Approximate Mass: 0.0005 amu
Location on Diagram: B (electrons are in orbitals around the nucleus)
Step 3: Fill in the properties for protons
Name: Proton
Symbol: p⁺
Charge: +1
Approximate Mass: 1.0 amu
Location on Diagram: A (protons are in the nucleus)
Final Answer
| name | symbol | charge | approximate mass (amu) | location on diagram |
|----------|--------|--------|------------------------|---------------------|
| electron | e⁻ | -1 | 0.0005 | B |
| proton | p⁺ | +1 | 1.0 | A |
| neutron | n⁰ | 0 | 1.0 | A |
