Atomic Number and Mass Number

Aug 31 2012So the Mass Number = The Atomic Number + the Number of Neutrons The Atomic Number is just the number of Protons and Atoms therefore 00:01:55 990 -- 00:02:02 990 The Mass Number = protons Get price

Why must you wait for an object to cool before you mass it

Oct 21 2007Why must you wait for an object to cool before you mass it ?
