Within an atom, where are electrons found?
A
In the nucleus, where they balance the positive charge of protons
B
In orbitals (the electron cloud) surrounding the nucleus
C
In the neutron cloud located just outside the nucleus
D
Evenly distributed throughout the nucleus and the surrounding space
Verified step by step guidance1
Understand the structure of an atom: it consists of a nucleus at the center, which contains protons and neutrons, and electrons that are found outside the nucleus.
Recall that protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
Recognize that electrons are not located inside the nucleus; instead, they exist in regions around the nucleus called orbitals, which collectively form the electron cloud.
Orbitals represent areas where there is a high probability of finding an electron, rather than fixed paths or orbits.
Therefore, electrons are found in the electron cloud (orbitals) surrounding the nucleus, balancing the positive charge of the protons but not residing within the nucleus itself.
