Let’s look at past year’s paper 1 june 2006.
Too small? Click here>> physics paper 1 2006.
This slideshow defines isotope and some of the elements with their isotopes.
Incidentally, we define the mass of all these periodic elements in terms of
unified atomic mass unit (u).
It is given that 1 u = 1.66 x 10 -27 kg.
Say that the atomic mass of silver (Ag) is 107.868 amu. This can also be expressed as
‘the relative atomic mass of silver is 107.868 g per mole”, or simply 107.868.
