|
Use chemical symbols to identify elements FE NA K |
iron sodium potassium |
|
|
|
3. Identify how many elements are in the periodic |
118 |
|
|
|
5. Identify the two elements where are liquids at room temperature |
bromine and mercury |
|
|
|
6. State the atomic number of an element using the data booklet helium nitrogen |
2 7 |
|
|
|
7. Explain what is meant by an element, a molecule and a compound |
element = substance made of one type of atom molecule = 2 atoms held together by chemical bonds compounds = 2 elements bonded |
|
|
|
8. Identify the seven diatomic elements |
Have hydrogen No nitrogen Fear flourine Of oxegyn Ice iodine Cold chlorine Beer bromine |
|
|
|
9. Explain what is meant by a solvent, solution and solute |
sugar+ water -> sugary water solute +solvent -> solution |
|
|
|
10. Explain the difference between a physical change and a chemical reaction |
physical chemical can’t reverse can reverse new product no new substance eg wood burning eg ice melting |
|
|
|
1.what are the 3 subatomic particles |
protons neutrons electrons |
|
|
|
2. State where the nucleus is found in an atom and which particles it contains |
the nucleus is the center of the cell and contains the neutrons and protons |
|
|
|
3. Explain why atoms have no overall charge despite containing charged particles |
the protons and electrons cancel each other out |
|
|
|
1. Write the electron arrangement and draw the electron arrangement diagram for the first 20 elements using the data booklet |
eg, 2,1,0 |
|
|
|
2. State how the number of outer electrons is related to group number for the main group elements |
the number of the outer electrons is the number of the group number eg helium is in group one so it has one outer electrons |
|
|
|
what is the atomic number equal to |
the number of protons |
|
|
|
what are the number of electrons equal to |
the number of protons |
|
|
|
true or false |the mass number is equal to the number of protons plus the number of neutrons in an atom |
true |
|
|
|
what method is used to determine if a metal is in a substance |
flame testing can be used |
|
|
|
State the elements present in compounds with names ending in -ide |
2 elements |
|
|
|
State the elements present in compounds with names ending in -ite |
2 elements plus oxegyn |
|
|
|
State the elements present in compounds with names ending in -ate |
same as -ite 2 plus oxegyn |
|
|
|
Identify the name of a compound given the elements it contains sodium chloride |
sodium and chlorine |
|
|
|
Construct the chemical formula for compounds with prefixes in their name carbon dioxide |
Co2 |
|
|
|
Construct the chemical formula for compounds containing two elements using the valency rules eg sodium chloride |
so to do this find the use SVSDF symbol Na Cl valency 1 1 swap 1 1 divide can’t simplify formaula NaCl don’t add the number one if u don’t know how to find the valency google it xxx |
|
|
|
Construct the chemical formula for compounds containing a transition metal using Roman numerals |
it’s the same but with roman numerals depict the number and that is your valency |
|
|
|
9. Write word equations to represent chemical reactions |
carbon + oxegyn ->carbon dioxi |
|
|
|
Write formula equations to represent chemical reaction |
C + O -> Co2 |
|
|
|
. Use state symbols correctly in formula equations |
state symbols follow a substance in your equation like so (g) = gas (s) solid (l) liquid (aq) aqueous aka a solution |
|
|
|
if any of these are wrong don’t be mad i j waffled and if there’s any missing ones i either can’t do them or can’t show them |
