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
0 1.0 a
+1 1.0 a
-1 0.0005 b

Explanation:

Step1: Identify sub - atomic particles

Sub - atomic particles in an atom are neutrons, protons, and electrons.

Step2: Match properties

Neutrons have a charge of 0, mass of approximately 1.0 amu and are in the nucleus (location A). Symbol is $n$. Protons have a charge of + 1, mass of approximately 1.0 amu and are in the nucleus (location A). Symbol is $p^+$. Electrons have a charge of - 1, mass of approximately 0.0005 amu and are in the electron - cloud (location B). Symbol is $e^-$.

Answer:

name	symbol	charge (in multiples of e)	approximate mass (amu)	location on diagram
proton	$p^+$	+ 1	1.0	A
electron	$e^-$	- 1	0.0005	B
