Resposta:
The structure of the atom is formed by the nucleus, which consists of two particles (protons and neutrons), and by the electrosphere, which holds the electrons. Atoms are infinitely small particles that make up all matter in the universe.
Hope this helps=)
more about it:
Over time, the idea of what the atomic structure would look like has been changing according to new discoveries made by scientists. You can learn more about this in the text Evolution of the Atomic Model.
A model is a representation of reality (not reality itself), thus, atomic models are representations of the main components of the atom and its structure and explain certain physical and chemical behaviors of matter. This is done because it is not yet possible for human beings to see an isolated atom even with ultramicroscopes.
To get an idea of how small the atom is, know that the smallest particle visible in a standard microscope contains more than ten billion atoms! The atom is so small that if we put a million of them side by side, we would not reach the thickness of a hair.
Resposta:
núcleo constituído por prótons e neutrons, e a eletrosfera que detém os elétrons
