Respuesta :

The majority of an atom's mass is located in the nucleus.

This is because much of the atom's mass is made up of neutrons and protons. Electrons do have mass, but they have so little of it that it is practically negligible.

The protons and neutrons are located in the nucleus, so that's where most of the mass is.
Hope this helps!

What is an Atomic Structure ?

An atom has electrons located in the outer shells carrying negative charge and around the nucleus which has protons and neutrons , The protons have positive charge and neutrons are neutral.

The atomic number is equal to the number of proton = no. of electrons present.

The atomic mass is equal to the mass of protons and neutrons as electrons have no mass.

So the majority of the mass of an atom is located in the nucleus of the atom.
