Wikipedia is gonna be your friend on this one - you won't get answers from this forum, just prods in the right direction

 

1. Copying/spelling Fluorine not Flourine - teachers always pick up on silly mistakes

 

2. The Periodic Table Hover over symbol (Li - Lithium) to get the name and and link to more details

 

3. Wikipedia has a page on each of the elements - such as this one for Carbon

 

4. No of Electron / No of Protons - read up a bit here Atom

 

5. No of Neutrons - read up on isotopes here Isotope and then look at each individual elements page Carbon Isotopes

 

6. Atomic Number and Atomic Mass - see relative atomic mass
