mass number The total number of protons and neutrons in the nucleus of an atom. For example, nitrogen has 7 protons and 7 neutrons in its nucleus, giving it a mass number of 14. The American Heritage® Student Science Dictionary, Second Edition. Copyright © 2014 by Houghton Mifflin Harc...
For welfare reasons, fattening on organic farms are raised on deep litter in the open with simple, flexible climate tents for shelter. Within this system, the (N) flow both during fattening of the from 17 to 100 kg liveweight in winter and during composting of the deep litter from the en...
Thomson (1910) identified a positive particle equal in mass to the hydrogen atom. Ernest Rutherford showed (1919) that nitrogen under alpha-particle bombardment ejects what appear to be hydrogen nuclei. By 1920 he had accepted the hydrogen nucleus as an elementary particle, naming it proton. ...

For example, nitrogen has seven protons in its nucleus and seven neutrons, supplying it with 14 masses. Q6 What is an atomic number and mass number? The number of protons and neutrons combines to give us the mass number of an atom. It is represented using the letter ‘A.’ The atomic...
