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.
Recognize that protons carry a positive charge, neutrons are neutral (no charge), and electrons are negatively charged particles found outside the nucleus.
Note that the nucleus occupies a very small volume compared to the entire atom, but it contains most of the atom's mass.
Conclude that the correct characteristic of the nucleus is that it contains protons and neutrons.
