Chemistry of P-Block Elements, Nitrogen, and Oxygen Families

Flashcards covering key concepts from the chemistry of p-block elements, focusing on nitrogen and oxygen families, properties, reactions, and preparation methods.

SO2

Sulfur dioxide, a colorless gas with a pungent odor, primarily produced by burning fossil fuels.

Ammonium Nitrate

A chemical compound, $NH_4NO_3$, commonly used in fertilizers and explosives.

PCl3

Phosphorus trichloride, a chemical compound used in the preparation of organophosphorus compounds.

Oxidizing Agent

A substance that gains electrons in a chemical reaction, causing another substance to be oxidized.

Acidic Character

The tendency of a substance to donate protons (H+) or accept electrons, increasing with a higher oxidation state.

Haber Process

An industrial method for synthesizing ammonia from nitrogen and hydrogen gas under high temperature and pressure.

Oxides of Nitrogen

Various chemical compounds formed between nitrogen and oxygen, such as $NO$ and $NO_2$.

Electron Affinity

The amount of energy released when an electron is added to a neutral atom to form a negative ion.

Hydrides of Phosphorus

Compounds formed between hydrogen and phosphorus, including $PH_3$ (phosphine).

Dithiionous Acid

An acid formed by sulfur, often represented as $H_2S_2O_4$.

Oxoacids of Sulfur

Acids that contain sulfur, oxygen, and hydrogen, such as sulfuric acid ($H_2SO_4$) and sulfurous acid ($H_2SO_3$).

Noble Gases

Inert gases found in Group 18 of the periodic table, including helium, neon, argon, krypton, xenon, and radon, known for their lack of reactivity.

Bond Angles

The angles between adjacent bonds in a molecule, important for determining molecular geometry.

Thionyl Chloride

A chemical compound used as a reagent in organic synthesis, known for releasing sulfur dioxide upon hydrolysis.
