Question

1. fill in the table with the correct information about the particles that make up an atom. (3 points)

particle type location mass charge
proton dropdown dropdown dropdown
neutron dropdown dropdown dropdown
electron dropdown dropdown dropdown

Explanation:

To fill the table, we recall the properties of atomic particles:

• Proton: Located in the nucleus. Mass is approximately $1$ atomic mass unit (amu) or $1.67\times10^{-27}\ \text{kg}$. Charge is $+1$ (or $+1.6\times10^{-19}\ \text{C}$).
• Neutron: Also in the nucleus. Mass is approximately $1$ amu (slightly more than proton, ~$1.675\times10^{-27}\ \text{kg}$). Charge is $0$ (neutral).
• Electron: Located in electron cloud (outside nucleus). Mass is approximately $1/1836$ amu (or $9.11\times10^{-31}\ \text{kg}$). Charge is $-1$ (or $-1.6\times10^{-19}\ \text{C}$).

We can now fill the table:

Particle Type	Location	Mass	Charge
Neutron	Nucleus	~$1\ \text{amu}$ (slightly more)	$0$ (neutral)
Electron	Electron Cloud	~$\frac{1}{1836}\ \text{amu}$	$-1$ (elementary charge)

Answer:

Particle Type	Location	Mass	Charge
Neutron	Nucleus	~$1\ \text{amu}$	$0$
Electron	Electron Cloud	~$\frac{1}{1836}\ \text{amu}$	$-1$
