1 2 3 4 Group 7 Explain the trend in boiling points of Cl 2 Br 2 and I 2 in terms of Van der Waals forces Explain reactivity of the halides with reference to negative ions atomic size shielding and nuclear attraction. Good resistance to many animal and vegetable oils as well as greases and oils in general Has low vapor and gas permeability making it suitable for gas and vacuum services Temperature Range 20 F to 212 F Size Range 5 to 12 Part Number 08 Resistant to Both elements and compounds are pure substances. Compounds are made by chemically combining 2 or more elements (the only way to break down a compound is by another chemical change-they break into smaller compounds and elements). Group 7.

Halogens are a series of non-metal elements located in group 7 of the periodic table. The term “halogen” means. “salt. -former”.. . All halogens . have seven electrons in their outermost. Fluorine is . added to toothpaste to prevent tooth . decay.. Sodium combines . with chlorine to make table . salt.. Chlorine is used in bleach and other chemicals to kill germs in swimming pools..

Bromine often isthe leading mineral commodity, in terms of value, produced in Arkansas. The Objectives of PresentationIntroduce the Chlorine Institute and CHLOREP Provide overview of the chemical properties, uses and hazards of chlorineProvide understanding of how to identify chlorine cylind AND CURRENT STATUS.

By: Celine, Julie, Andrew & Kaitlin . What is Fluorine Dating, and how is it used?. fluorine: (n.). flu-o-rine. a nonmetallic chemical, usually found in a pale yellow flammable gas form. It is a hazardous, poisonous gas that is absorbed by bones that lies under soil.. 1). 2). 3). 4). Group 7. Explain the trend in boiling points of Cl. 2. , . Br. 2. , and I. 2. in terms of Van . der. Waals’ forces.. Explain reactivity of the halides with reference to negative ions, atomic size, shielding and nuclear attraction. Ja. -Ho Koo. EAS 6792 Term project. Introduction. Tropospheric. ozone depletion event (ODE) usually happens in spring,. . polar. . region.. ODE looks strongly related to the amount of atmospheric bromine chemistry based on the heterogeneous reaction (Barrie et al., 1988). Give two properties of other Group 2 compounds that decrease down the group. [2]. ease of thermal decomposition of carbonates; solubility of carbonates;. insolubility of hydroxides/nitrates; AW/.
