Atomic structure is the distribution of electrons in atomic orbitals. The number of electrons in an atomic orbital is determined by the Aufbau principle, which states that electrons fill orbitals in order of increasing energy. The Pauli exclusion principle states that no two electrons in an atom can have the same set of quantum numbers.
The 3p5 electron configuration is found in the element Chlorine (Cl). This means that Chlorine has 3 electrons in its 3p subshell. The 3p subshell is part of the third energy level of the Chlorine atom.
Chlorine is a halogen element. Halogens are highly reactive non-metallic elements that form salts with metals. Chlorine is the second lightest halogen, after fluorine. It is a pale green gas at room temperature and has a pungent, irritating odor.
Chlorine is an important industrial chemical. It is used to make a variety of products, including PVC, bleach, and hydrochloric acid. Chlorine is also used as a disinfectant in swimming pools and water treatment plants.
