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
proton				select	select
neutron				select	select

Explanation:

Step1: Identify the particle with charge -1

The particle with charge -1 (in multiples of \( e \)) is the electron. So the first row (name) should be "electron".

Step2: Determine the symbol of electron

The symbol for electron is \( e^- \) (or sometimes just \( e \), but in the context of subatomic particles, \( e^- \) is common).

Step3: Determine the charge of neutron and proton

Neutron has a charge of 0 (in multiples of \( e \)), and proton has a charge of +1 (in multiples of \( e \)).

Step4: Determine the approximate mass of neutron and proton

The approximate mass of neutron is 1 amu, and the approximate mass of proton is also 1 amu (electron is ~0.0005 amu as given).

Step5: Determine the location of particles

In the atom diagram, "A" is the nucleus (where protons and neutrons are located), and "B" is the electron cloud (where electrons are located). So electron is at location B, proton and neutron are at location A.

Answer:

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