Andrew Kolano Chemical Bonding .The melting and boiling points of ionic compounds are much higher compared to those of the covalent compounds. .Ionic compounds are hard and crystal-like, while covalent compounds are softer and more flexible. .Covalent compounds are more flammable when compared to ionic compounds. .Ionic compounds are more soluble in water than covalent compounds. 4. Find 5 Lewis Structures and copy and paste them on your page. Determine their molecular geometry.
 * 1) What is a covalent bond? A bond formed by the shareing of electrons between atoms. (chem book)
 * 2) What is an ionic bond? A eletrostatic attractoin that binds oppsitely charged ions together
 * 3) List 5 differences between ionic and covalent compounds (Ex. high or low boiling and melting points, sharing or transferring electrons, etc.)..Ionic compounds are formed by the transfer of electrons that are positively and negatively charged, whereas, covalent compounds are formed by sharing the electrons.





Name- Hydrofluoric acid, formula- HF - I found the formula for hydrofluoric acid by finding that fluoric (fluoride) is -1 and hydro (hydrogen) is pos. 1 so they cancel each others charges out and make the formula HF. - Watch yourself Andrew. Fluoric doesn't give you fluoride, hydrofluoric gives you fluoride. Just like hydrosulfuric acid is H2S (S = sulfide, Rule #1) and sulfuric acid is H2SO4 (SO4 = sulfate, Rule #3).

formula- HNO2, Name- Nitrous acid - First i found that the formula follows rule number 2. Rule number 2 is, when the anion name ends in -ite, the acid name is the stem of the anion with the suffix -ous. - ** Very nice. **

Name- Manganese (3) Fluoride, Formula- MnF3 - First i used the symbols and names of common metal ions with more than one ionic charge chart. Next,i found Manganese that has a 3 positive charge andfluorine with a negative 1 charge. - ** Excellent **
