In a simplified model of the atom, where are electrons primarily found?
A
In the spaces between protons inside the nucleus
B
In the electron cloud (energy levels) surrounding the nucleus
C
Only in the outermost shell, never in inner energy levels
D
In the nucleus, where protons and neutrons are located
Verified step by step guidance1
Understand that in the simplified atomic model, electrons are not located inside the nucleus but rather in regions around it.
Recall that the nucleus contains protons and neutrons tightly packed together, so electrons cannot be found there.
Learn that electrons exist in areas called energy levels or shells, which form an electron cloud surrounding the nucleus.
Recognize that electrons can occupy multiple energy levels, not just the outermost shell; inner shells also contain electrons.
Conclude that electrons are primarily found in the electron cloud (energy levels) surrounding the nucleus, not inside the nucleus or only in the outermost shell.
