What i learnt from chapter 3 and 4

From Binary Covalent Nomenclature tutorial, i learnt the following formulae. water - H2O, ammonia - NH3, methane - CH4, ethane - C2H6 , propane - C3H8. I also learnt that Hydrogen atoms always form one covalent bond, and halogen atoms.

From the cation names and formulas tutorial, i learnt that metalic atoms tend to lose electron while, non-metalic atoms tend to gain eloctron, resulting the positive cation and negative anion to form ionic bonding.
