Atomic nitrogen number densities in the upper thermosphere measured by the open source neutral mass spectrometer (OSS) on Atmosphere Explorer-C during 1974 and part of 1975 have been used to construct a global empirical model at an altitude of 375 km based on a spherical harmonic expansion. The...

To calculate the total number of electrons in the nitrate ion (NO₃⁻), we can follow these steps:Step 1: Identify the atomic number of nitrogen and oxygen - The atomic number of nitrogen (N) is 7. - The atomic number of ox
The atomic numbers of some of the most famous atoms are hydrogen (1), oxygen (8), carbon (6), nitrogen (7), and gold (79) as seen in the picture. The number in parenthesis is the atomic number and also the number of protons that would be in a single atom of that element. Eleme...
Atomic number (Z) Integer equal to the number of protons in a nucleus; the order of an element in the periodic table. Atomic weight or nuclear mass number (A) An integer equal to the sum of the number of protons Z and neutrons N. Isobar Member of a set of nuclides of the same at...
Atomic Number and Mass Number • The atomic number of an element is the same as the number of protons in an atom of that element. Atoms of different elements have different numbers of protons. Hydrogen has 1 proton so its atomic number is 1. Silver has 47 protons so its atomic number...
To find the percent abundance of the two isotopes of nitrogen (Nitrogen-14 and Nitrogen-15) given their atomic masses and the average atomic mass of nitrogen, we can follow these steps:1. Define Variables: Let the percent ab
