Why are you materialists so adamant about it? Modern physics has disproved the concept entierly. Berkeley was right.
Immaterialism is the only way to correctly understand the nature of reality. Everything you perceive by the senses is illusory, your ideas about what you perceive are the ideas in God's mind.
There is no electron orbiting around the nucleus of an atom, only a probability wave of possible outcomes where the electron can exist in the shell.
