Guida verificata passo dopo passo1
Recall the basic structure of an atom, which consists of a nucleus and electrons surrounding it.
Understand that the nucleus is the central part of the atom and contains subatomic particles called protons and neutrons.
Remember that protons have a positive charge, neutrons have no charge (neutral), and electrons have a negative charge.
Recognize that the nucleus occupies a very small volume compared to the entire atom, which is mostly empty space where electrons are found.
Conclude that the nucleus has a positive charge overall due to the protons, and it contains both protons and neutrons, but not electrons.
