What is the electronic configuration of nitrogen [Atomic number=7, Atomic mass=14]? Q. Molecular mass of Nitrogen is 28. Its atomic mass is 14. Find the atomicity of Nitrogen.
29. Copper. 63.546. 30. Zinc. 65.38. The Molecular mass of an element can be calculated by adding the atomic masses of each of its constituents. There are many ways to find the atomic mass of an element, but the easiest way is to look it up on the periodic table of elements.
Problem – 1: Find the element mass number whose atomic number is 18 and the neutron number is 20. Solution: Number of protons = 18. Number of Neutrons = 20. Atomic mass Number = Number of protons + number of neutrons. A = 20 + 18. Mass number (A) = 38. More topics in Atomic Mass Formula. Avogadro’s Law Formula.
The atomic mass of Nitrogen N = 14. 0067. Molar Mass of N 15 is 15. 001. Molar Mass of N 14 is 14. 003. Let the fraction of N 15 = x. Then the fraction of N 14 = 1-x. Step 2: Calculation of total atomic mass of Nitrogen. Now the total atomic mass of Nitrogen = F r a c t i o n o f N 15 × M o l a r M a s s o f N 15 + F r a c t i o n o f N 14 × ...
1.9. Some of the trends in the modern periodic table with respect to group 15 elements of the p-Block elements are discussed below. 1. Electronic Configuration. The valence shell electronic configuration plays a major role in how an element behaves. The valence electron shell configuration of group 15 elements is ns 2 np 3.
The de Broglie wavelength of nitrogen molecule is (Atomic mass of nitrogen = 14.0076 u, h = 6.63 × 10 − 27 J s, k B = 1.38 × 10 − 23 J K − 1, 1 u = 1.66. × 10 − 27 k g) Q. Assuming the nitrogen molecule is moving with r.m.s. velocity at 400 K , the de-broglie wavelength of nitrogen molecule is close to :
The average mass is the relative atomic mass, which can be easily calculated from the percentage composition ( % abundance). An element’s relative atomic mass, Ar, is calculated as follows: The mass numbers of its isotopes; The abundance of these isotopes; The formula that can be used to calculate the relative atomic mass:
