Modern atomic theory states that the atom is a diffuse cloud surrounding a small, dense nucleus. identify which particle is in the nucleus.

note-Unlike the planetary model, our model view is that the electrons move around the nucleus in an electron cloud. Modern atomic theory states that the atom is a diffuse cloud surrounding a small, dense nucleus. Identify which particle is in the nucleus. note-Neutron is a particle in the nucleus.

Neutrons and Protons

Explanation:

The atom is made of 3 particles: electrons, protons and neutron.

The diffuse cloud is made of electrons, that have a negative charge and a smaller mass than the neutrons and protons.

The nucleus is made of neutrons, that have no electric charge, and protons that have a positive charge and repels the electrons. Both neutrons and protons have a bigger mass than the electrons.
