Answer 2

Chemical Element with Atomic Number 15

Position in the Periodic Table: The chemical element with atomic number 15 is phosphorus. It is located in the 3rd period and the 15th group of the periodic table. Phosphorus is a nonmetal.

Electron Configuration: The electron configuration of phosphorus is [Ne] 3s^2 3p^3.

Atomic Structure: Phosphorus has 15 protons and 15 electrons in its neutral state. It has 3 electron shells and 5 electrons in its outer shell.

Properties of the Pure Substance: Phosphorus exists in several allotropic forms. The most common forms are white phosphorus, red phosphorus, and black phosphorus. White phosphorus is a highly toxic, waxy, and transparent solid with a garlic-like odor. Red phosphorus is a less reactive and more stable form, while black phosphorus is a recently discovered allotrope with unique electronic properties.

Minimum and Maximum Oxidation States: The minimum oxidation state of phosphorus is -3, and the maximum oxidation state is +5. Phosphorus commonly exhibits oxidation states of -3, +3, and +5 in its compounds.

Composition and Properties: Phosphorus is a highly reactive nonmetal. It readily forms compounds with other elements, such as phosphates, which are essential for life as they are a key component of DNA, RNA, and ATP. Phosphorus compounds are also widely used in fertilizers, detergents, and various industrial processes.
