Guida verificata passo dopo passo1
Recall the structure of an atom: it consists of a nucleus and an electron cloud surrounding it.
Understand that the nucleus contains particles called protons and neutrons, which are collectively known as nucleons.
Electrons are negatively charged particles that orbit the nucleus in various energy levels and are not found inside the nucleus.
For an argon atom, like any other atom, the nucleus specifically contains protons (positively charged) and neutrons (neutral charge).
Therefore, the particles found in the nucleus of an argon atom are protons and neutrons.
