4) The proton and the nucleus are attracted to a negative charge since they have positive charges
5) The number of positive and negative particles in the models will differ.
6) The solar system model is shown in the image attached
7) The diameter of an atom is about
to
times larger than the diameter of its nucleus.
What are the particles in the atom?
Protons are positively charged particles that are located in an atom's nucleus. An atom's identity is determined by its number of protons, which is also known as its atomic number.
Alongside protons, neutrons are neutral, or uncharged, particles found in the nucleus. Protons and neutrons are similar in mass.
Particles with a negative charge that travel in electron shells or energy levels around the nucleus are electrons . Compared to protons and neutrons, electrons are substantially lighter in mass.
