Want this question answered?
In the nucleus of the atom, along with neutrons. The electrons are found around the nucleus. If the atom was the size of a Baseball stadium, the nucleus would be the size of a baseball! Most of the space in an atom is taken up by the electron cloud which surrounds the nucleus. That is why atoms are actually mostly empty space.
Think of the sun as the nucleus and the oort cloud (past pluto) as where the electron orbitals start. The size (volume) of the nucleus is tiny compared to the size (volume) of the atom (defined by the extent of the electron cloud).
The atom itself would be the size of an NFL stadium.

The size of an atom refers to the typical distance from the nucleus to the boundary of the surrounding cloud of electrons.

nucleus is found at the centre of an atom. however the size of the nucleus is about 10-12 nm
Assuming you're talking about the nucleus of an atom, the nucleus is very small relative to the atom's volume as a whole. However, it makes up nearly all of an atom's mass, because it contains all the protons and neutrons. So, relative to the total atom, the nucleus is very small and very dense.
The nucleus has most of the mass (weight) of an atom. The size of the atom, however, is related to its electron cloud (i.e. to the electrons that orbit around the nucleus)
Because there are electrons around the nucleus which form a cloud the nucleus is a part of this cloud roughly atom is 8000 times bigger than an average nucleus.
I need to know also
The atom's nucleus consists of protons and neutrons. The nucleus is relatively small and very dense at that.
