what does an atom of lead look like? what are the parts that compose of the atom?

help me pls

I'm right c'here.

An atom (of anything) consists of a nucleus, where most of the mass of an atom resides, and shells outside the nucleus. The nucleus is composed of protons and neutrons. Electrons are in the outside shells. The number of protons and the number of electrons are equal. I have no idea what an atom of lead, or any other atoms for that matter, looks like since I have not seen one. To my knowledge, no one has seen one. We know about atoms, however, by experiments that have been conducted over the years. I hope this helps.
