Concept introduction:
Electronic configuration represents the arrangement of electrons in an atom. The sublevels are filled according to their increasing energy. The electrons are firstly filled into the sublevel having lowest energy. The sublevel closest to the nucleus has the lowest energy. The trend of filling of electrons according to the energy of sublevels is given below.
The electronic configuration up to the electronic configuration of the last noble gas is represented with the symbol of noble gas in square brackets. This notation is known as core notation.

INTRODUCTORY CHEMISTRY-STD.GDE.+SOL.MAN
- The atomic masses of the natural isotopes of neon are 19.99244u, 20.99395u, and 21.99138u . The average of these three masses is 20.99259u . The atomic mass of neon is listed as 20.1797u on the periodic table. Which isotope do you expect is the most abundant in nature? Explain. When neon gas is within an activated gas discharge tube, reddish-orange light is emitted.arrow_forwardCalcium metal reacts with cold water as follows: Ca+2H2OCa(OH)2+H2 Magnesium metal does not react with cold water. What behavior toward cold water would you predict for strontium and barium?
