This element does not exist, the mass is far too high and would need about 140-170 protons (and electrons!) to 'keep' it together.
Number 107 could have a mass of about 265 but a measured value couldn't be found in extended periodic tables.
According to wikipedia http://en.wikipedia.org/wiki/File:Island-of-Stability.png
- a nice picture of probability on 'ever finding' isotopes, there is an 'island of stability', in the middle of which number 126 (with isotopic mass 310 and 322) is the most probable to stay long enough to be detected. However it is still far from known how to synthesize this element.
Nitrogen has a gram atomic mass of 14.0067, an atomic number of 7, and the chemical symbol N.
The atomic weight is14.00674
For finding the atomic mass of any element, we have to get sum of number of protons & number of neutrons. Atomic Mass (A) : p+n. * p = no. of protons. * n = no. of neutrons. Therefore, atomic mass of oxygen is 15.
By taking the wieghted averages of naturally occurring isotopes of that element. :)
N = nitrogen nitrogen has an atomic mass of 14.00674 amu Hope this helps :)
The atomic mass number A is the total number of protons and neutrons in an atom's nucleus. For nitrogen (N), the atomic number (number of protons) is 7. If it has 7 neutrons (designated as "7n"), then the atomic mass number A would be 14 (7 protons + 7 neutrons).
Nitrogen is a non metal element. Atomic mass of it is 64.
The atomic mass of NH4Cl can be calculated by adding the atomic masses of each element in the compound. The atomic masses of nitrogen (N) is 14.01, hydrogen (H) is 1.01, and chlorine (Cl) is 35.45. By adding these values together, the atomic mass of NH4Cl is 53.46 g/mol.
weight...'
equal to number of protons
By N, I assume you mean Nitrogen. Nitrogen's Atomic number is 7, and its atomic mass is ~14.011.
The atomic mass NUMBER equals the number of protons and neutrons in an atom. DO NOT confuse this with the mass of an atom.
