These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements. 14. i) The weight ratio of elements carbon, hydrogen & nitrogen in a compound of molecular mass 104 is 18:2:7 What is its molecular formula? Insulators, on the other hand, are made of a wide variety of materials depending on factors such as the desired resistance. Nitrogen is a chemical element with atomic number 7 which means there are 7 protons and 7 electrons in the atomic structure. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in atomic mass units (u). If the molecular weight of the compound is 108 and the molecular formula is CxHyNz , then find the value of x,y and z . Nitrogen is the fifth most abundant element in the Universe. Elemental nitrogen is a colorless, odorless, tasteless and mostly inert diatomic gas at standard conditions, constituting 78.08% percent of Earth’s atmosphere. It's found naturally as a molecule, each containing two nitrogen atoms. So, it will seek out other atoms that also want to complete the octet rule so they can share valence electrons. Nitrogen is the chemical element in the periodic table that has the symbol N and atomic number 7. Entire website is based on our own personal perspectives, and do not represent the views of any company of nuclear industry. However, its compounds are … To understand the difference between metals, semiconductors and electrical insulators, we have to define the following terms from solid-state physics: A possible crystal structure of Nitrogen is hexagonal structure.
