Structure of atom

Understand the Problem

The question is asking about the components and organization of an atom, which includes protons, neutrons, and electrons, as well as their arrangement in relation to the nucleus.

Answer

An atom consists of a small nucleus with protons and neutrons, surrounded by electrons.

An atom consists of a small, positively charged nucleus containing protons and neutrons, surrounded by a cloud of negatively charged electrons.

Answer for screen readers

An atom consists of a small, positively charged nucleus containing protons and neutrons, surrounded by a cloud of negatively charged electrons.

More Information

The nucleus is incredibly dense and contains most of the atom's mass. Despite its small size, less than one-ten-thousandth the size of the atom, its electrostatic force plays a critical role in atomic interactions.

Tips

Avoid confusing the nucleus's charge with the overall charge of the atom, which is neutral when the number of protons equals the number of electrons.
