Is neon (element 10) gas a metal/metalloid/nonmetal, discovery date and year, properties (atomic number, melting point, electron configuration), what is it used for
The chemical element of atomic number 10, an inert gaseous element of the noble gas group. It is obtained by the distillation of liquid air and is used in fluorescent lamps and advertising signs Fluorescent lighting or signs (whether containing neon or some other gas) - the lobby of the...
Neon is a chemical element; it has symbol Ne and atomic number 10. It is the second noble gas in the periodic table.[11] Neon is a colorless, odorless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It was discovered along with krypton and xenon...
Neon is the lasing element in He-Ne laser. The lasing transition(632.8nm) is from 3s to 2p. In the energy level diagram there is one 1.15μm transition from 2s to 2p. But we studied that 2s orbital have lower energy than 2p then how it is possible, in the energy diagram, 2s level...
Using the average atomic masses, calculate the mass (in amu) of 125 carbon atoms. Using the average atomic masses, calculate the mass (in amu) of 1 atom of magnesium. What is the average atomic weight of an element of the two kno...
chemical element, one of the noble gases, 1898, coined by its discoverers, Sir William Ramsay and Morris W. Travers, from Greekneon, neuter ofneos"new" (seenew); so called because it was newly discovered. They also discovered its property of emitting colored light when electrified in a se...
Neon is a noble gas present in group 18 and period 2 of the periodic table. It is a p block element with atomic number and atomic mass of 10 and 20 respectively. At a typical 20°C temperature; it remains in a gaseous state. It has a density of 0.000825 g/cm^3. The melting poin...
