Hi Maybe couple of you must be knowing this. But someone asked me about this today. I myself discovered it in class 12th. Till then, I knew the entire periodic table but if you asked me suddenly that what is the 3rd element of group 16, I would have taken atleast 30 seconds or even more to give the answer. Coz periodic table without a pattern is very hard to remember. Then, I came to know of this code to remember the entire periodic table. After this, I could read out the entire s and p clock in less than 30 seconds in my mind. NOTE : You need to be familiar with the periodic table to make full use of thisNOTE: Please take the hint from the Sound the words as well a

Explain tliefollowilig 1. The radius of anion is greater than atom while that of cation is lesser than atom. 2.Half-filled and fully-filled orbitals are more stable. 3. The first ionization energy of carbon atom is greater than that of boron whereas the reverse is true for the second ionization energy. Explain. 4. The first ionization potential of N is maximum as compared to those of C and 0. 5. The ionic size of Cl- ions is greater than that of K+, though the two Ions are isoetectronic, Give reasons. 6. The electron affinity of chlorine is greater than that of F. 7. The electron affinity of sulphur is greater than that of oxygen. 8. The electron aff

HEAVIEST ELEMENT FINALLY DISCOVERED?] (Be Patient while reading) Element 118, the heaviest element yet found, was produced through collisions that fused together Californium and Calcium atoms. Although element 118 is too unstable to detect directly, the presence of daughter elements resulting from the decay of element 118 gave clues to its fleeting existence. Element 118 has been createed in experiments conducted at the Flerov Lavoratory of Nuclear Reactions in Dubna, Russia by a collaboration of researchers from Russia's Joint Institute for Nuclear Reasearch andthe Lawrence Livermore National Laboratory in California. The new element is the heavi
