The particles which make up an atom
What do we use the relative atomic mass
have different masses:
not the actual mass of an atom?
Particle
Relative Mass
Proton
Neutron
What is the relative atomic mass of
electron
oxygen?
What is an isotope?
Give two similarities of isotopes and two
differences:

compound?
how you would work out its relative
formula mass: (Mg =24, Cl = 35.5)
What is a mole?
What does Avogadros number tell us?
How do we work out the % element in a
What is a molecular formula?
compound?
What is an empirical formula?
Complete the table you would use to work
out an empirical formula:
moles
÷ by smallest
Complete the table you would use to work To work out a number of moles we can
out an reacting mass calculation:
use the following triangle:
Element/compound
Ratio from equation
The formula for working out percentage
yield is:
The yield of a reaction is:
