Our family: The Halogens
Creators: Tyreka Tripp, Aaron Gholston, John Gonzales
Family Tree (youngest to oldest)
Halogens
Chlorine (1774)
Iodine (1811)
Bromine (1826)
Fluorine (1886)
Astatine (1940)
Group 17
Chlorine 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.

Iodine (nonmetal)
Parent: Bernard CourtoisBirth Place and Date: 1811 France
FRANCE
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
Chemical Description
Valence= 7Ion= I^-1, -1
Reactivity=reactiveCompounds=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
Bromine (non metallic)
Who’s my DADDY? –Bromine was born to a proud parent named Antoine J. Balard (1802–
1876).
It’s a boy!!!!
I am so
happy!!!
Where was I born?
• Bromine was born in the France in 1826
FRANCEFRANCE
FRANCE
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.I look nice! look
at my strong
electrons.
My Chemical Description
Valence number=7 Ion= -1
Oxidation number= -1Reactivity= very reactive
Compounds of Bromine= Ethylene dibromide, Carbon tetrabromide, Lead Bromate.
Positive vs. Negative
Positives • 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
Negatives • Dangers, cautions needed-
If too much is used could cause a toxic condition
• It could cause serve acne• Irritating odor• Causes tears
Fluorine (non-metallic)
• Parent: Georgius Agricola• Birth Place and Date: Germany in 1530
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
Chemical Description
Valence= #7Ion= 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.
Astatine (non metal)• 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.
