Question

1. fill in the table.

subatomic particle charge mass location in atom

Explanation:

Step1: Recall proton details

Proton has a charge of + 1 elementary - charge, mass of approximately 1 atomic mass unit (amu), and is located in the nucleus.

Step2: Recall neutron details

Neutron has a charge of 0, mass of approximately 1 amu, and is located in the nucleus.

Step3: Recall electron details

Electron has a charge of - 1 elementary - charge, mass of approximately $\frac{1}{1836}$ amu, and is located in the electron - cloud outside the nucleus.

Answer:

Subatomic Particle	Charge	Mass	Location in atom
Neutron	0	~1 amu	Nucleus
Electron	- 1	$\frac{1}{1836}$ amu	Electron - cloud outside nucleus
