How to Locate Neon 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 10 to find Neon 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 Neon on periodic table look for cross section of group 18 and period 2 in the modern periodic table.

Neon History

The element Neon was discovered by W. Ramsay and W. Travers in year 1898 in United Kingdom. Neon was first isolated by W. Ramsay and W. Travers in 1898. Neon derived its name from the Greek neos, meaning 'new'.

Discovery Date 1898 in United Kingdom
First Isolation 1898
Isolated by W. Ramsay and W. Travers

In June 1898 Ramsay separated a new noble gas from liquid argon by difference in boiling point.

Neon Uses

Neon is the 4th most abundant element in the entire universe. Till now, the most prominent use of the element today is used in advertising signs. When coaxed with electricity, the glass glows, leading to its use in the sign industry and high-voltage indicators and lasers. Liquid neon is an important cryogenic refrigerant.

Crystal Structure of Neon

The solid state structure of Neon is Face Centered Cubic.

The Crystal structure can be described in terms of its unit Cell. The unit Cells repeats itself in three dimensional space to form the structure.

Unit Cell Parameters

The unit cell is represented in terms of its lattice parameters, which are the lengths of the cell edges Lattice Constants (a, b and c)

π/2 π/2 π/2

The positions of the atoms inside the unit cell are described by the set of atomic positions ( xi, yi, zi) measured from a reference lattice point.

The symmetry properties of the crystal are described by the concept of space groups. All possible symmetric arrangements of particles in three-dimensional space are described by the 230 space groups (219 distinct types, or 230 if chiral copies are considered distinct.

Ground State Electronic Configuration of Neon - neutral Neon atom

Abbreviated electronic configuration of Neon

The ground state abbreviated electronic configuration of Neutral Neon atom is [He] 2s2 2p6. The portion of Neon 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 2p6, electrons in the outermost shell that determine the chemical properties of the element.

Electrons are filled in atomic orbitals as per the order determined by the Aufbau principle, Pauli Exclusion Principle and Hund’s Rule.

  • As per the Aufbau principle the electrons will occupy the orbitals having lower energies before occupying higher energy orbitals. According to this principle, electrons are filled in the following order: 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p…
  • The Pauli exclusion principle states that a maximum of two electrons, each having opposite spins, can fit in an orbital.
  • Hund's rule states that every orbital in a given subshell is singly occupied by electrons before a second electron is filled in an orbital.

    Spectral Lines of Neon - Atomic Spectrum of Neon

    A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from an excess or deficiency of photons in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules.

    Spectral lines are the result of interaction between a quantum system and a single photon. A spectral line may be observed either as an emission line or an absorption line.

    Spectral lines are highly atom-specific, and can be used to identify the chemical composition of any medium. Several elements, including helium, thallium, and caesium, were discovered by spectroscopic means. They are widely used to determine the physical conditions of stars and other celestial bodies that cannot be analyzed by other means.

    Regulatory and Health - Health and Safety Parameters and Guidelines

    The United States Department of Transportation (DOT) identifies hazard class of all dangerous elements/goods/commodities either by its class (or division) number or name. The DOT has divided these materials into nine different categories, known as Hazard Classes.

    Non-flammable, non-toxic* gases

    NFPA 704 is a Standard System for the Identification of the Hazards of Materials for Emergency Response. NFPA is a standard maintained by the US based National Fire Protection Association.

    The health (blue), flammability (red), and reactivity (yellow) rating all use a numbering scale ranging from 0 to 4. A value of zero means that the element poses no hazard; a rating of four indicates extreme danger.
