  1. Our family: The Halogens Creators: Tyreka Tripp, Aaron Gholston, John Gonzales

  2. Family Tree (youngest to oldest) Group 17

  3. Chlorine CL • Parent: Scheele • Born in the year 1774 and discovered in Sweden • Gender Non metal • PD1: 17P, 17E, 7V, +1 • PD2: 293 K, -34.6 °C, -100.98 °C • CD: 7V, No reactivity • Positive Effects: Chlorine is usually added to drinking water and swimming pools to make the water safer for people. • Negative effects: Acute exposure to low levels of chlorine results in eye, nose, and throat irritation, sneezing, excessive salivation, general excitement, and restlessness. Higher concentrations causes difficulty in breathing, violent coughing, nausea, vomiting, cyanosis, dizziness, headache, choking, laryngeal edema, acute tracheobronchitis, chemical pneumonia.

  4. Iodine (nonmetal) Parent: Bernard Courtois Birth Place and Date: 1811 France FRANCE

  5. Physical Description • protons and electrons= 53 • Neutrons= 74 • Density= 4.933 g/cm³, • Boiling point= 457.4 K (184.3 °C, 363.7 °F), • Melting point= 386.85 K (113.7 °C, 236.66 °F), • Characteristics: nonmagnetic, slightly soluble

  6. Chemical Description Valence= 7 Ion= I^-1, -1 Reactivity=reactive Compounds=Copper(I) iodide (CuI), Hydroiodic acid (HI), Iodic acid (HIO3) • Positive Attributes -To combat iodine deficiency • Negative Attributes – Can be radioactive that will causes cancers

  7. Bromine (non metallic) It’s a boy!!!! Who’s my DADDY? –Bromine was born to a proud parent named Antoine J. Balard (1802–1876). I am so happy!!!

  8. Where was I born? • Bromine was born in the France in 1826 FRANCE FRANCE FRANCE

  9. What do I look like? Physical Description • Density= @ 293 K: 3.119 g/cm3 • Boiling point= 58.78 °C - 331.93 °K • Melting point= -7.2 °C - 265.95 °K • Specific heat= 0.473J/gK • Heat (thermal) conductivity= 0.00122 W/cmK I look nice! look at my strong electrons.

  10. My Chemical Description Valence number=7 Ion= -1 Oxidation number= -1 Reactivity= very reactive Compounds of Bromine= Ethylene dibromide, Carbon tetrabromide, Lead Bromate.

  11. Positive vs. Negative Positives Negatives Dangers, cautions needed- If too much is used could cause a toxic condition It could cause serve acne Irritating odor Causes tears • Photographic chemicals, dyes, pests controls and vegetable oil • In the past Bromine was used as a sedative. It is naturally occurring and is a liquid at room temperature

  12. Fluorine (non-metallic) • Parent: Georgius Agricola • Birth Place and Date: Germany in 1530

  13. Physical Description Melting Point: 53.53 K (-219.62°C or -363.32°F) Boiling Point: 85.03 K (-188.12°C or -306.62°F) Density: 0.001696 grams per cubic centimeter Phase at Room Temperature: Gas, most reactive elements • Protons and Electrons: 9 • Neutrons: 10

  14. Chemical Description Valence= #7 Ion= F^-1 Oxidation number= -1, Reactivity= very reactive Compounds= Oxide, Hydrides, Chlorides • Positive Attributes: Used in tooth paste • Negative Attributes: Fluorine is highly toxic and corrosive.

  15. Astatine (non metal) . :At: .. • Astatine named by the Greek as unstable. • Astatine was adopted by D.R. Corson. • Astatine was born in the year of 1940 • Gender: Non Metal • PD1: 85P, 85E, 7VE, +1 Charge • PD2: D293K, 337.0CBP, No reactivty • CD: 7, -1, -1, No reactivity, • Positive effects: The possible role of astatine in tumor therapy and nuclear medicine • Negative effects: It turns into a radioactive decay.
