Trivial name of Oxygen is chalcogens*. Know everything about Oxygen Facts, Physical Properties, Chemical Properties, Electronic configuration, Atomic and Crystal Structure
History of Oxygen
The element Nitrogen was discovered by Daniel Rutherford in year 1772 in United Kingdom . Nitrogen derived its name from the Greek word nitron and ‘-gen’ meaning ‘niter-forming’
Nitrogen is a chemical element with symbol N and atomic number 7. It is the lightest pnictogen and at room temperature, it is a transparent, odorless diatomic gas. Nitrogen is a common element in the universe, estimated at about seventh in total abundance in the Milky Way and the Solar System.
How to Locate Oxygen on Periodic Table
Periodic table is arranged by atomic number, number of protons in the nucleus which is same as number of electrons. The atomic number increases from left to right. Periodic table starts at top left ( Atomic number 1) and ends at bottom right (atomic number 118). Therefore you can directly look for atomic number 7 to find Nitrogen on periodic table.
Another way to read periodic table and locate an element is by using group number (column) and period number (row). To locate Nitrogen on periodic table look for cross section of group 15 and period 2 in the modern periodic table.
Oxygen Atomic Structure and Orbital Properties
Nitrogen atoms have 7 electrons and the electronic shell structure is [2, 5] with Atomic Term Symbol (Quantum Numbers) 4S3/2.
Atomic Structure of Oxygen
Ground State Electronic Configuration of Oxygen - neutral Oxygen atom
The ground state electronic configuration of Neutral Nitrogen atom is [He] 2s2 2p3. The portion of Nitrogen configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [He]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used.This is important as it is the Valence electrons 2s2 2p3, electrons in the outermost shell that determine the chemical properties of the element.
