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 electron ( e^- ) +1 1.0 a neutron ( n^0 ) 0 1.0 a proton ( p^+ ) +1 1.0 a

Explanation:

Step1: Analyze electron properties

Electrons have a charge of -1 (not +1), mass ≈ 0 amu (not 1.0), and are located in electron clouds (B, not A).

Step2: Analyze neutron properties

Neutrons have charge 0, mass ≈ 1.0 amu, and are in the nucleus (A) – this part was correct.

Step3: Analyze proton properties

Protons have charge +1, mass ≈ 1.0 amu, and are in the nucleus (A) – this part was correct.

For electron:

• Charge: -1
• Mass: 0
• Location: B

For neutron: (correct as is)

• Charge: 0
• Mass: 1.0
• Location: A

For proton: (correct as is)

• Charge: +1
• Mass: 1.0
• Location: A

Answer:

name	symbol	charge (in multiples of e)	approximate mass (amu)	location on diagram
neutron	$n^0$	0	1.0	A
proton	$p^+$	+1	1.0	A
