What is a physical property |
A property of an element having nothing to do with chemicals. |
|
|
|
What is a chemical property |
A characteristic of a substance that's observed. Includes. Reaction to acids, water and heat Ability to burn Behaviour in hair

|
What is Chemical bonding |
When 2+ elements function as a unit called compounds. |
2+ |
|
|
What are the two different types of chemical bonding. |
Ionic: the transferring of electrons (the metal to the non metal) Convalent: the sharing of electrons |
Share and transfer |
|
|
What do electrons in ionic compounds do? |
They - electrons to form cations (+). |
|
|
|
What do electrons in molecular compounds do? |
They gain electrons, therefore creating anions (-). |

|
|
What are some properties of ionic compounds. |
They are the binding of cations and anions. Metals and non. Form a lattice structure Solid at room temp. Dissolve in water Form stable compounds. Have a high melting point. Conductive when a liquid. |

|
|
|
What are some properties of molecular compounds. |
The bond of two metals or anions No lattice structure (crystal). All 3 states at room temp. Doesn't dissolve in water. Low melting point. Easy to break. |
|
|
|
When naming and writing ionic compounds. |
It's a metal and non. Remember to switch the ion charges especially on polyatomics. Don't use prefixes. Watch for multivalents. Cation is the first element. The anion is second. * when writing the state. Look for solubility and day solid or aqueous. Don't put the state for Molecular compounds. |
|
|
|
When naming and writing molecular compounds |
It's two non metals. Use prefixes for naming the first and last elements. High solubility= aqueous Low= solid Mono di tri tetra penta hexa hepta octa nona deca. |
|
|
|
Properties of bases |
React with acids to form solids. Dissolve in water to release OH- ions. Bitter Turn red litmus paper blue. Phenolphthalein purple/pink. Aqueous. Slippery. |
ARBB Bitter. |
|
|
IUPAC naming |
Add aqueous in front Usually add hydrogen after. Wrote as an ionic compound. |
|
|
|
Common Naming |
Ate to ick Ite to ous Ide and out hydro and ic at the end. Add acid at the end. Reverse to get IUPAC name. Watch for OH, it's a base |
|
|
|
Formula writing for acids and bases. |
Write as an ionic formula. Put (aq) in brackets after. |
|
|
|
What are binary compounds. What are the two different compounds formed by |
Binary compounds are formed by 2 elements.
Binary ionic compounds are formed by a metal and non metal
Binary molecular compounds are formed by two non metals. |
|
|
|
What property of baking soda makes it easier to clean up spills |
The carbonate has a crystal structure that cleans surfaces easily and it also neutralized acids and bases to eliminate odour. |
