Nitrogen is a chemical element that has the symbol N, atomic number of 7 and atomic mass 14.00674 u. Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.08% by volume of Earth's atmosphere. Many industrially important compoun...
作者: V Thiel 摘要: Nitrogen is a nonmetal element with atomic number 7 and atomic mass of 14.00674 u. It was discovered in 1772 by Daniel Rutherford (1749–1819), a Scottish physician, botanist and chemist (Weeks, 1934). DOI: 10.1007/978-1-4020-9212-1_157 收藏...

Mass Number The sum of the number of protons and neutrons of an atomic nucleus. In other words, it's the sum of the number of nucleons in an atom. Relative Atomic Mass The ratio of the average mass per atom of an isotope to 1/12 the mass of a carbon-12 atom. Relative atomic mas...
An atomic mass unit is defined as 1/12 the mass of a Carbon-12 nuclide. We use the concept to investigate and present quantities. The mass of an atom of an element is the mass number given the unit "amu".Answer and Explanation: ...
