All the elements of similar categories show a lot of similarities and differences in their chemical, atomic, physical properties and … It is almost always found in the -1 oxidation state. Model of Chlorine crystal structure. CHAPTER 3: CRYSTAL STRUCTURES & PROPERTIES • tend to be densely packed. • have the simplest crystal structures. Chlorine is a halogen gas.

Let us begin our investigation of crystal lattice structure and unit cells with the most straightforward structure and the most basic unit cell.
High concen- trations of chloride are found in the Dead Sea, and about 1.9% of the mass of the world’s sea water is chloride. • have several reasons for dense packing:-Typically, only one element is present, so all atomic radii are the same. Chlorine dioxide | ClO2 | CID 24870 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, … -Nearest neighbor distances tend to be small in order to lower bond energy.

In nature, chlorine is found as the chloride ion that is deposited in the earth or dissolved in the oceans.

-Metallic bonding is not directional.

Name: Chlorine Symbol: Cl Atomic Number: 17 Atomic Mass: 35.4527 amu Melting Point:-100.98 °C (172.17 K, -149.764 °F) Boiling Point:-34.6 °C (238.55 K, -30.279997 °F) Number of Protons/Electrons: 17 Number of Neutrons: 18 Classification: Halogen Crystal Structure: Orthorhombic Density @ 293 K: 3.214 g/cm 3 Color: green Atomic Structure Chlorine is an ingredient in many everyday items and is an important chemical in water purification, disinfectants, … To visualize this, imagine taking a large number of identical spheres, such as tennis balls, and arranging them uniformly in a container.

Chlorine gas was used against humans in World War I as a killing agent.

Crystal Structure: The Diatomic Chlorine molecules arrange themselves in an orthohombic structure.

Compare Sodium and Chlorine Compare elements on more than 90 properties.

This is because it has a strong tendency to gain an electron and achieve a noble gas electron configuration.
