The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
The search for hydrocarbon molecular biomarkers in Archean metasediments is of prime importance for deciphering the early evolution of life. Suitable criteria are required to identify promising targets for further molecular biomarkers. Possible criteria include the Hydrogen-to-Carbon (H/C) atomic ratio ...
