How to find whether a given base is Strong or Weak?

most acids and bases are assigned a value called the pH value
the pH value can be defined as negative logarithim to the base 10 of the H+ ion concentration [-log to base 10 H+]
the pH can take any value from 0 to 14
any value below 7 makes the soln acidic and any value above 7 makes the soln basic
so higher the pH more basic the soln and lower the pH more acidic the soln
please correct me if i am wrong and nudge me if you have any doubts
but if you wan't a more explinative ans with deeper understanding please refer a good chemistry book

see for the conjugate acid of that base
if the acid is strong ,then the corresponding base will be weak

Strong bases have more electron density concentrated on one atom.

More e- density on one atom?
What if we have only one base, and we have to say whether it is strong or weak?? then with what should we compare??
CONJUGATE ACID: Well, how will we see whether that acid is strong or not?
