Question:What are the main components of every atom?

Atoms are composed of a small central nucleus surrounded by a cloud of electrons.

The following diagram represent the atom.

The black sphere represents the nucleus, the red spheres represent the electrons and the blue line represent the paths of the electrons as the orbit the nucleus.

The nucleus and electrons are not drawn to scale.

The diameter of the nucleus is only 1/10000th of the atomic diameter.

The rest of the volume of the atom is occupied by the electrons paths; the electrons themselves have no size.
