Best Answer: Ok...here it goes... Socrates was noted for his dedication to careful reasoning. He sought genuine knowledge rather than mere victory over an opponent. He employed the same logical tricks developed by the Sophists to a new purpose, the pursuit of TRUTH.
The atomic mass of a specific atom or molecule is determined by using an experimental technique called mass spectrometry. This technique separates the different isotopes of atoms to allow determination of the percent abundance or isotopic composition of the element in the given sample.
This unit is actually not the mass of a proton or neutron in grams but is a mass ratio based on the element carbon. An amu is defined as 1/12 of the mass of a carbon atom. Proton...Protons have a positive charge. The number of protons in a nucleus determines the identity of the atom (element) and this number is called the atomic number. The actual mass of a proton has been determined to be 1.673 x 10-24 gram. Scientists use the metric system of measurement where the standard unit for mass is the gram.
