Why Big Fr and Hungry F

1. Why is francium the biggest element with the lowest IE and EN?
      Francium is the biggest element with the lowst ionization energy because Francium is the largest atom which means the valence electrons are further from the nucleous which makes it easier to lose them. Fr has the lowest electronegativity because the atom is bigger and less attractive than a smaller atom's nucleous would be, therefore the ionization energy and the electronegativity both depend upon the size of the atom.

2. Why is helium the smallest atom with the highest IE?
   A helium atom has the highest ionization energy because smaller atoms have a stronger gravitational pull on electrons which makes it harder to lose valence electrons.

3. Why don't noble gases have an EN value?
   Full outer shell, don not gain electrons, no charge because they gain no electrons.

4. Why does Florine have the highest EN?
   F only needs one more valence electron and is a halogen. Halogens are the most reactive non-metals which makes it easier to gain the one Valence electron needed.

Sulfer, a great element!

Sulfer Dioxide

        Sulfer, Zwavel in Dutch, or Schwefel in German got its name from the latin word sulfur which means brimstone. It has 16 protons, neutrons, and electrons. The naturally occuring isotopes of sulfer are

32-S Abundence: 94.93 (31) Average atomic mass: 31.97207070 (25) 

33-S Abundence: 0.76 (2) Average atomic mass: 32.97145843 (23)

34-S Abundence: 4.29 (28) Average atomic mass: 33.96786665 (22)

36-S Abundence: 0.02 (1) Average atomic mass: 35.96708062 (27)

       There are three electron shells. Shell one has two, shell two has eight, and shell three has six. My atomic radius is 100 pm or picometers. Sulfer is odorless, tasteless, light yellow, and solid. It is a reactive element that under certain circumstances combines with all other elements except gases, gold, and platinum. Sulfer has a specific gravity of 2.07 (rhombic form) or 1.96 (monoclimic form). Sulfur dioxide, SO2, is a colorless gas with an irritating, choking odor. It is produced naturally in volcanoes and in geysers. No one really knows who discovered sulfur. Sulfur was known in ancient times and is referred to in Genesis in the Bible. English translations of the Bible refer to sulfur as brimstone. Sulfur was also known to the Chinese in the 6th century BC in its natural form. In the 3rd century the Chinese discovered how to isolate sulfur from the mineral pyrite, commonly known as fool’s gold. After isolation, the Chinese began using sulfur in medicine and sulfur has become a part of traditional Chinese medicine. Sulfer is used in some medicines. It is also used in some soaps, gunpowder ,used on matches, fertilizers ,fungicides, and pesticides. I obtaine most of my information from the website http://www.webelements.com/, the symbol for sulfur is S and the atomic mass number is 16. 

Here I Am!

Hi, this is my blog. Welcome. this is for chem class. I will use this when needed.

The things i love are animals, food, T.V., videogames, and my computer. i especially love my family including my two cats Ky and Sam.

The things I hate are homework, doing work, and blogging :)

I dream of becomeing a doctor. all done.
