One of my possible career aspirations is to be a commercial airline pilot. Contratry to most people's believe it is not very difficult to be a pilot. The requirement for this is to attain a cpl(commercial pilot license). The minimum age to be a commercial pilot in singapore is 26 years of age due to the limited talent pool needed for the air force. Pilots have to go through yearly medical check ups and tests depending on wad kind of pilot they are.

weaknesses and strengths in chemistry

hmmm... i guess i make lots of careless mistakes.. my weakness wouldn't really be my understanding of the topics.. it would be my lack of practise due to my lackadaisical attitude. so i guess i have to practise and study more! strengths??.... practical.... i'm super meticulous!!

The key things related to the topics below



Binary Covalent Nomenclature: - A binary covalent compound is a pure substance that consists of two non-metallic elements.

an example would be water which is h2O.



-how to name a binary covalent compound using prefixes such as di or tri.

e.g N2O3 would be dinitrogen trioxide



-how to convert names to formulae

e.g dinitrogen trioxide is N2O3



Cation names and formulas:

- Metallic atoms tend to lose electrons and form cations.



-They usually lose a certain number of electrons to have the same stable electronic configuration as the nearest noble gas.



-The names of monatomic cations always start with the name of the metal, sometimes followed by a Roman numeral to indicate the charge of the ion.



Anion names and formulae

- Nonmetallic atoms tend to gain electrons and form anions.



-nonmetallic atoms form anions in order to get the same number of electrons as the nearest noble gas.



-The monatomic anions are named by adding -ide to the root of the name of the nonmetal that forms the anion.
