attraction to the positively charged nucleus
An atom is composed of a central nucleus containing a varying number of protons and neutrons, and electrons, which orbit the nucleus in shells. The majority of an atoms volume comes from the space between the central nucleus and the surrounding electrons.
In general, the nucleus and the electron cloud are the two distinct features of the volume of the atom. The nucleus is home to the proton(s) and whatever neutrons are present, and the electron cloud is where the electrons all hang out. The nucleus, with its protons and neutrons, has most of an atom's mass concentrated there. The electrons are relatively far away, and the orbits they describe give the atom its "shape" by defining its volume in space.
Electrons do surrounding the atom and rotate around the nucleus.
Atoms don't neccassarilly have space inside of them. Atoms are very small peices of matter, orbiting around each other. The nucleus contains neutrons and protons, and electrons orchit this nucleus. I am not sure what you exactly mean by "space in an atom" but atoms are very small, and take up hardly any space.
Electrons
A lot of space and very small electrons. There is between 95% and 99% empty space around the nucleus, before you get to the electron shell of the next atom.
The space around the nucleus of an atom is called the electron cloud. The electron cloud is the space in which the electrons of that atom travel. Compared to the nucleus, the electron cloud is enormous.
This space is only absolute vacuum.
shells or orbit
the cytoplasm is the space in a plant cell surrounding the nucleus
an atom has two subatomic particles which are neutrons and protons in the nucleus or "center" and electrons surrounding the nucleus in orbitals, "orbit like" regions of space outside the nucleus.
The nucleus contains the majority of the mass in an atom. The nucleus contains the protons and neutrons, which each have a relative mass of 1 amu. The electrons surround the nucleus and have a relative mass of 0 amu.
attraction to the positively charged nucleus
If you are talking about an atom, the nuclues which is composed of protons and neutrons, is surrounded by electrons. Which make up a cloud around the outside of the nucleus.
