Verified step by step guidance1
Begin by understanding the basic structure of an atom, which consists of a nucleus and an electron cloud. The nucleus contains protons and neutrons, while the electron cloud contains electrons.
Recall the charge of each subatomic particle: protons are positively charged, neutrons are neutral, and electrons are negatively charged.
Identify where each type of subatomic particle is located within the atom: protons and neutrons are found in the nucleus, while electrons are found in the electron cloud surrounding the nucleus.
Examine the options given in the problem. You need to match the description of an electron with its charge and location within the atom.
Select the option that correctly describes an electron as a negatively charged subatomic particle found in the electron cloud.
