1 Fluorine (F) Highly toxic, refrigerants gas

2

3 Basic Information  Name: Fluorine  Symbol: F  Atomic Number: 9  Atomic Mass: 18.998 amu  Electron Configuration: 2,7  Boiling Point: -188.14 ۫ C  Melting Point: -219.62 ۫ C  Diatomic element

4 Facts  Derived from the Latin word “fleure”, which means flow  Discovery: In 1886, by Henri Moissan  Obtained from: Mineral fluorite

5 Description  Greenish pale yellow acidic gas  Most reactive of the non-metal → combined with most other elements  13 th most common element in the crust

6 Uses  Helps other materials to burn → Rocket fuels  Alone it is poisonous → used in fluorine compound → nuclear industry  Toothpaste → Average human body contains hundredth of ounce of fluorine  Damage ozone layer 

7 Bromine (Br) volatile, mobile, dangerous reddish- brown liquid

8

9 Basic Information  Name: Bromine  Symbol: Br  Atomic Number: 35  Atomic Mass: 79.904 amu  Electron Configuration: 2,8,18,7  Boiling Point: 58.78 ۫ C  Melting Point: -7.2 ۫ C  Diatomic element

10 Facts  Derived from the Greek word “bromos”, which means stench  Discovery: In 1826, by Antoine J. Balard from SALT WATER  Poisonous  Obtained from: SEA WATER

11 Description  A reddish-brown liquid  The that is a at normal room conditions.  Causes painful burns only non-metal liquid

12 Uses  Very poisonous → Pesticides  Photographic film  Malfunctioning of nervous system → Disturbances in genetic materials  Organic Bromine can cause damage to organs → Can even cause cancer !!!!

13 Iodine (I) bluish-black, lustrous solid

14

15 Basic Information  Name: Iodine  Symbol: I  Atomic number: 53  Atomic mass: 126.90 amu  Electron configuration: 2,8,18,18,7  Boiling Point:183 ۫ C  Melting Point: 113.7 ۫ C  Diatomic element

16 Facts  Derived from the Greek word iôdes, which means “violet”  Discovery: In 1811, by Bernald Courtois from SULFURIC ACID  Required in humans  Obtained from: sodium and potassium compounds

17 Description  When solid: looks metallic, grayish-black or violet-dark gray color.  As a gas: violet color, with a harsh, unpleasant odor.  Sublimation → Never exists as a liquid

18 Uses → First Aid

19 Iodine for body function  A naturally occurring mineral for your body to function normally.  Iodine Body Functions: Heat and Energy production Metabolism of fat Physical and Mental development Production of Thyroid hormone

20 Iodine Deficiency IIodine Deficiency Disorders FFor FOOD SOURCES high in IODINE try: - Seafood - Kelp - Iodized Salt
