Question

Drag each label to the correct location. Each label can be used more than once.

Answer 1

Electron

Electric charge -1

It's found outside the nucleus

It's mass is negligible

Proton

It's mass is 1

The electric charge is +1

it's found in the nucleus

Neutron

It's mass is 1

The electric charge is 0

It's found in the nucleus

Answer 2

Explanation:

Every atom consists of three sub-atomic particles which are protons, neutrons and electrons.

Inside the nucleus of an atom, there will be only protons and neutrons. Whereas electrons revolve around the nucleus of an atom.

Protons have a positive charge, neutrons have no charge and electrons have a negative charge.

Mass of these subatomic particles are as follows.

Proton : $1.672623 \times 10^{-27} kg$

Neutron : $1.674929 \times 10^{-27} kg$

Electron : $9.109390 \times 10^{-27} kg$

Hence, we can conclude that the properties of sub-atomic particles are matched as follows.

• Electron :

- Its electrical charge is -1.

- It's found outside the nucleus.

- Its mass is negligible.

• Proton:

- Its electrical charge is +1.

- Its found inside the nucleus.

- It's mass is 1.

• Neutron:

- Its electrical charge is 0.

- It's found inside the nucleus.

- It's mass is 1.
