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.

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

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.
