proton
( \text{p}^+ )

Explanation:

Step1: Recall subatomic particle properties

Protons (\(p^+\)) have +1 charge, ~1 amu mass, located in nucleus (A). Neutrons (\(n^0\)) have 0 charge, ~1 amu mass, located in nucleus (A). Electrons (\(e^-\)) have -1 charge, ~0.0005 amu mass, located in electron cloud (B).

Step2: Match with table

• Proton: symbol \(p^+\), charge +1, mass 1.0 amu, location A (nucleus).
• Neutron: symbol \(n^0\), charge 0, mass 1.0 amu, location A (nucleus).
• Electron: symbol \(e^-\), charge -1, mass 0.0005 amu, location B (electron cloud).

Answer:

name	symbol	charge (in multiples of e)	approximate mass (amu)	location on diagram
Neutron	\(n^0\)	0	1.0	A
Electron	\(e^-\)	-1	0.0005	B
