Here are the essential concepts you must grasp in order to answer the question correctly.
Subatomic Particles
Subatomic particles are the fundamental constituents of atoms, which include protons, neutrons, and electrons. Protons are positively charged particles found in the nucleus, neutrons are neutral particles also located in the nucleus, and electrons are negatively charged particles that orbit the nucleus. Understanding these particles is essential for grasping atomic structure and chemical behavior.

Atomic Structure
Atomic structure refers to the arrangement of subatomic particles within an atom. The nucleus, composed of protons and neutrons, is at the center, while electrons occupy various energy levels or shells around the nucleus. This structure is crucial for understanding how atoms interact, bond, and form molecules, which are the building blocks of matter.

Electron Configuration
Electron configuration describes the distribution of electrons in an atom's energy levels and orbitals. Electrons are arranged in a way that minimizes energy, filling lower energy levels first before moving to higher ones. This configuration influences an atom's chemical properties and reactivity, making it a key concept in chemistry and physics.
