BRAINLIESTTT ASAP!! PLEASE HELP ME :)

Answer 1

The nucleus of an atom contain protons and neutrons, which make up most of the mass of an atom.

The answer would be 2 and 3 ( 2nd answer choice)

Answer 2

Answer: Option (b) is the correct answer.

Explanation:

In an atom there will always be three sub-atomic particles which are protons, neutrons and electrons.

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

Thus, we can conclude that out of the given options locations 2 and 3 are likely to have subatomic particles with the greatest mass.
