Detailed explanation-1: -Nucleus: the center of the atom that contains the mass of the atom. Electron cloud: region that surrounds the nucleus that contains most of the space in the atom.

Detailed explanation-2: -An atom is composed of two regions: the nucleus, which is in the center of the atom and contains protons and neutrons, and the outer region of the atom, which holds its electrons in orbit around the nucleus.

Detailed explanation-3: -The two parts of an atom are the nucleus and the electron cloud. The nucleus is composed of protons and neutrons, densely packed in the nucleus and held together by nuclear forces. The electron cloud is an area around the nucleus where the electrons orbit the nucleus in different shells.

Detailed explanation-4: -An electron cloud represents the area around an atom’s nucleus where electrons are most likely to be found. It is a sphere that surrounds the microscopic nucleus, although it is often rendered as a ring in two-dimensional pictures.

Detailed explanation-5: -Atomic Orbital: A region around an atom’s nucleus where an electron is likely to be found.
