Answer:
Use electron cloud model.
Step-by-step explanation:
Electrons are arranged in a shells around the nucleus in an atom. Protons and neutrons are found in the nucleus while electrons are found surround the nucleus. Electron closest to the nucleus will have lowest energy or when electrons away from the nucleus will have high energy. The
is the formula to find maximum number of electrons in the shell.
The electron cloud model explains the use of atoms. It determines cloud of electrons surrounds the nucleus of the atom. Scientist use the electron cloud model to describe the possible locations of electrons around the nucleus.
